CERTAIN INVESTMENT LIMITATIONS AND GUIDELINES

The following limitations and guidelines are considered at the time of purchase,
under normal circumstances, and are based on a percentage of the fund's net
assets unless otherwise noted. This summary is not intended to reflect all of
the fund's investment limitations.

. The fund will invest at least 80% of its assets in securities guaranteed or
sponsored by the U.S. government.

. The fund may invest up to 20% of its assets in non-government securities
rated AAA or Aaa by a nationally recognized statistical ratings
organization or unrated securities determined to be of equivalent quality
by the fund's investment adviser.

* * * * * *

The fund may experience difficulty liquidating certain portfolio securities
during significant market declines or periods of heavy redemptions.

DESCRIPTION OF CERTAIN SECURITIES AND INVESTMENT TECHNIQUES

The descriptions below are intended to supplement the material in the prospectus
under "Investment objective, strategies and risks."

U.S. GOVERNMENT OBLIGATIONS -- U.S. government obligations are securities backed
by the full faith and credit of the U.S. government. U.S. government obligations
include the following types of securities:

U.S. TREASURY SECURITIES -- U.S. Treasury securities include direct
obligations of the U.S. Treasury, such as Treasury bills, notes and bonds.
For these securities, the payment of principal and interest is
unconditionally guaranteed by the U.S. government, and thus they are of the
highest possible credit quality. Such securities are subject to variations
in market value due to fluctuations in interest rates, but, if held to
maturity, will be paid in full.

FEDERAL AGENCY SECURITIES BACKED BY "FULL FAITH AND CREDIT" -- The
securities of certain U.S. government agencies and government-sponsored
entities are guaranteed as to the timely payment of principal and interest
by the full faith and credit of the U.S. government. Such agencies and
entities include the Government National Mortgage Association (Ginnie Mae),
the Veterans Administration (VA), the Federal Housing Administration (FHA),
the Export-Import Bank (Exim Bank), the Overseas Private Investment
Corporation (OPIC), the Commodity Credit Corporation (CCC) and the Small
Business Administration (SBA).

OTHER FEDERAL AGENCY OBLIGATIONS -- Additional federal agency securities are
neither direct obligations of, nor guaranteed by, the U.S. government. These
obligations include securities issued by certain U.S. government agencies and
government-sponsored entities. However, they generally involve some form of
federal sponsorship: some operate under a government charter; some are backed by
specific types of collateral; some are supported by the issuer's right to borrow
from the Treasury; and others are supported only by the credit of the issuing
government agency or entity. These agencies and entities include, but are not
limited to: Federal Home Loan

U.S. Government Securities Fund -- Page 2
<PAGE>

Bank, Federal Home Loan Mortgage Corporation (Freddie Mac), Federal National
Mortgage Association (Fannie Mae), Tennessee Valley Authority and Federal Farm
Credit Bank System.

These securities will be rated AAA by Standard & Poor's Corporation or Aaa by
Moody's Investors Service or unrated but determined to be of equivalent quality.

PASS-THROUGH SECURITIES -- The fund may invest in various debt obligations
backed by pools of mortgages. Principal and interest payments made on the
underlying asset pools backing these obligations are typically passed through to
investors, net of any fees paid to any guarantor of the securities. Pass-through
securities may have either fixed or adjustable coupons. These securities
include:

"MORTGAGE-BACKED SECURITIES" -- These securities may be issued by U.S.
government agencies and government-sponsored entities, such as Ginnie Mae,
Fannie Mae and Freddie Mac. The payment of interest and principal on
mortgage-backed obligations issued by U.S. government agencies may be
guaranteed by the full faith and credit of the U.S. government (in the case
of Ginnie Mae), or may be guaranteed by the issuer (in the case of Fannie
Mae and Freddie Mac). However, these guarantees do not apply to the market
prices and yields of these securities, which vary with changes in interest
rates.

COLLATERALIZED MORTGAGE OBLIGATIONS (CMOS) -- CMOs are also backed by a
pool of mortgages or mortgage loans, which are divided into two or more
separate bond issues. CMOs issued by U.S. government agencies are backed by
agency mortgages. Payments of principal and interest are passed through to
each bond issue at varying schedules resulting in bonds with different
coupons, effective maturities and sensitivities to interest rates. Some
CMOs may be structured in a way that when interest rates change, the impact
of changing prepayment rates on the effective maturities of certain issues
of these securities is magnified. CMOs may be less liquid or may exhibit
greater price volatility than other types of mortgage or asset-backed
securities.

INFLATION-INDEXED BONDS -- The fund may invest in inflation-indexed bonds issued
by governments, their agencies or instrumentalities and corporations. The
principal value of this type of bond is adjusted in response to changes in the
level of the consumer price index. The interest rate is fixed at issuance as a
percentage of this adjustable principal. The actual interest income may
therefore both rise and fall as the level of the consumer price index rises and
falls. In particular, in a period of deflation the interest income would fall.
While the interest income may adjust upward or downward without limit in
response to changes in the consumer price index, the principal has a floor at
par, meaning that the investor receives at least the par value at redemption.

Repayment of the original bond principal upon maturity (as adjusted for
inflation) is guaranteed in the case of U.S. Treasury inflation-indexed bonds,
even during a period of deflation. However, the current market value of the
bonds is not guaranteed and will fluctuate.

REPURCHASE AGREEMENTS -- The fund may enter into repurchase agreements under
which the fund buys a security and obtains a simultaneous commitment from the
seller to repurchase the security at a specified time and price. Repurchase
agreements permit the fund to maintain liquidity and earn income over periods of
time as short as overnight. The seller must maintain with the fund's custodian
collateral equal to at least 100% of the repurchase price, including accrued
interest, as monitored daily by the investment adviser. The fund will only enter
into

U.S. Government Securities Fund -- Page 3
<PAGE>

repurchase agreements involving securities in which it could otherwise invest
and with selected banks and securities dealers whose financial condition is
monitored by the investment adviser. If the seller under the repurchase
agreement defaults, the fund may incur a loss if the value of the collateral
securing the repurchase agreement has declined and may incur disposition costs
in connection with liquidating the collateral. If bankruptcy proceedings are
commenced with respect to the seller, realization of the collateral by the fund
may be delayed or limited.

FORWARD COMMITMENT, WHEN ISSUED AND DELAYED DELIVERY TRANSACTIONS -- The fund
may enter into commitments to purchase or sell securities at a future date. When
the fund agrees to purchase such securities, it assumes the risk of any decline
in value of the security from the date of the agreement. If the other party to
such a transaction fails to deliver or pay for the securities, the fund could
miss a favorable price or yield opportunity, or could experience a loss.

The fund will not use these transactions for the purpose of leveraging and will
segregate liquid assets that will be marked to market daily in an amount
sufficient to meet its payment obligations in these transactions. Although these
transactions will not be entered into for leveraging purposes, to the extent the
fund's aggregate commitments in connection with these transactions exceed its
segregated assets, the fund temporarily could be in a leveraged position
(because it may have an amount greater than its net assets subject to market
risk). Should market values of the fund's portfolio securities decline while the
fund is in a leveraged position, greater depreciation of its net assets would
likely occur than if it were not in such a position. The fund will not borrow
money to settle these transactions and, therefore, will liquidate other
portfolio securities in advance of settlement if necessary to generate
additional cash to meet its obligations. After a transaction is entered into,
the fund may still dispose of or renegotiate the transaction. Additionally,
prior to receiving delivery of securities as part of a transaction, the fund may
sell such securities.

The fund may also enter into reverse repurchase agreements and "roll"
transactions. A reverse repurchase agreement involves the sale of a security by
a fund and its agreement to repurchase the security at a specified time and
price. A "roll" transaction involves the sale of mortgage-backed or other
securities together with a commitment to purchase similar, but not identical,
securities at a later date. The fund assumes the risk of price and yield
fluctuations during the time of the commitment. The fund will segregate liquid
assets that will be marked to market daily in an amount sufficient to meet its
payment obligations under "roll" transactions and reverse repurchase agreements
with broker-dealers (no collateral is required for reverse repurchase agreements
with banks).

RESTRICTED OR ILLIQUID SECURITIES -- The fund may purchase securities subject to
restrictions on resale. Restricted securities may only be sold pursuant to an
exemption from registration under the Securities Act of 1933 (the "1933 Act"),
or in a registered public offering. Where registration is required, the holder
of a registered security may be obligated to pay all or part of the registration
expense and a considerable period may elapse between the time it decides to seek
registration and the time it may be permitted to sell a security under an
effective registration statement. Difficulty in selling such securities may
result in a loss to the fund or cause it to incur additional administrative
costs.

Securities (including restricted securities) not actively traded will be
considered illiquid unless they have been specifically determined to be liquid
under procedures adopted by the fund's board of trustees, taking into account
factors such as the frequency and volume of trading, the commitment of dealers
to make markets and the availability of qualified investors, all of which can

U.S. Government Securities Fund -- Page 4
<PAGE>

change from time to time. The fund may incur certain additional costs in
disposing of illiquid securities.

CASH AND CASH EQUIVALENTS -- These include (a) commercial paper (for example,
short-term notes with maturities typically up to 12 months in length issued by
corporations, governmental bodies or bank/corporation sponsored conduits
(asset-backed commercial paper)) (b) short-term bank obligations (for example,
certificates of deposit, bankers' acceptances (time drafts on a commercial bank
where the bank accepts an irrevocable obligation to pay at maturity)) or bank
notes, (c) savings association and savings bank obligations (for example, bank
notes and certificates of deposit issued by savings banks or savings
associations), (d) securities of the U.S. government, its agencies or
instrumentalities that mature, or may be redeemed, in one year or less, and (e)
corporate bonds and notes that mature, or that may be redeemed, in one year or
less. Investments in these securities are subject to the fund's ratings
guidelines.

VARIABLE AND FLOATING RATE OBLIGATIONS -- The interest rates payable on certain
securities in which the fund may invest may not be fixed but may fluctuate based
upon changes in market rates or credit ratings. Variable and floating rate
obligations bear coupon rates that are adjusted at designated intervals, based
on the then current market rates of interest or credit ratings. The rate
adjustment features tend to limit the extent to which the market value of the
obligations will fluctuate.

LOANS OF PORTFOLIO SECURITIES -- The fund is authorized to lend portfolio
securities to selected securities dealers or other institutional investors whose
financial condition is monitored by the investment adviser. The borrower must
maintain with the fund's custodian collateral consisting of cash, cash
equivalents or U.S. government securities equal to at least 100% of the value of
the borrowed securities, plus any accrued interest. The investment adviser will
monitor the adequacy of the collateral on a daily basis. The fund may at any
time call a loan of its portfolio securities and obtain the return of the loaned
securities. The fund will receive any interest paid on the loaned securities and
a fee or a portion of the interest earned on the collateral. The fund will limit
its loans of portfolio securities to an aggregate of 33-1/3% of the value of its
total assets, measured at the time any such loan is made.

The fund does not currently intend to engage in this investment practice over
the next 12 months.

* * * * * *

PORTFOLIO TURNOVER -- Portfolio changes will be made without regard to the
length of time particular investments may have been held. Short-term trading
profits are not the fund's objective, and changes in its investments are
generally accomplished gradually, though short-term transactions may
occasionally be made. High portfolio turnover involves correspondingly greater
transaction costs in the form of dealer spreads or brokerage commissions, and
may result in the realization of net capital gains, which are taxable when
distributed to shareholders.

Fixed-income securities are generally traded on a net basis and usually neither
brokerage commissions nor transfer taxes are involved. Transaction costs are
usually reflected in the spread between the bid and asked price.

U.S. Government Securities Fund -- Page 5
<PAGE>

A fund's portfolio turnover rate would equal 100% if each security in the fund's
portfolio were replaced once per year. The fund's portfolio turnover rates for
the fiscal years ended August 31, 2006 and 2005 were 146% and 104%,
respectively. Portfolio turnover increased in 2006 as the fund sought to protect
shareholder principal and seek attractive investment opportunities during a
period of rising interest rates. See "Financial highlights" in the prospectus
for the fund's annual portfolio turnover rate for each of the last five fiscal
years.

FUNDAMENTAL POLICIES AND INVESTMENT RESTRICTIONS

FUNDAMENTAL POLICIES -- The fund has adopted the following fundamental policies
and investment restrictions, which may not be changed without approval by
holders of a majority of its outstanding shares. Such majority is defined in the
Investment Company Act of 1940, as amended (the "1940 Act"), as the vote of the
lesser of (a) 67% or more of the outstanding voting securities present at a
shareholder meeting, if the holders of more than 50% of the outstanding voting
securities are present in person or by proxy, or (b) more than 50% of the
outstanding voting securities. All percentage limitations are considered at the
time securities are purchased and are based on the fund's net assets unless
otherwise indicated. None of the following investment restrictions involving a
maximum percentage of assets will be considered violated unless the excess
occurs immediately after, and is caused by, an acquisition by the fund.

These restrictions provided that the fund may not:

1. Purchase any security (other than securities issued or guaranteed by the
U.S. government or its agencies or instrumentalities ("U.S. government
securities") if, immediately after and as a result of such investment, more than
5% of the value of the fund's total assets would be invested in securities of
the issuer;

2. Invest 25% or more of the value of its total assets in the securities of
issuers conducting their principal business activities in the same industry,
except that this limitation shall not apply to U.S. government securities;

3. Invest in companies for the purpose of exercising control or management;

4. Knowingly purchase securities of other investment companies, except in
connection with a merger, consolidation, acquisition, or reorganization;

5. Buy or sell real estate or commodities or commodity contracts in the
ordinary course of its business; however, the fund may purchase or sell readily
marketable debt securities secured by real estate or interests therein or issued
by companies which invest in real estate or interests therein, including real
estate investment trusts;

6. Acquire securities subject to restrictions on disposition imposed by the
Securities Act of 1933, if, immediately after and as a result of such
acquisition, the value of such restricted securities and all other illiquid
securities held by the fund would exceed 10% of the value of the fund's total
assets;

7. Engage in the business of underwriting securities of other issuers, except
to the extent that the disposal of an investment position may technically cause
it to be considered an underwriter as that term is defined under the Securities
Act of 1933;

U.S. Government Securities Fund -- Page 6
<PAGE>

8. Make loans, except that the fund may purchase readily marketable debt
securities and invest in repurchase agreements and make loans of portfolio
securities. The fund will not invest in repurchase agreements maturing in more
than seven days (unless subject to a demand feature) if any such investment,
together with any illiquid securities (including securities which are subject to
legal or contractual restrictions on resale) held by the fund, exceeds 10% of
the value of its total assets;

9. Sell securities short, except to the extent that the fund contemporaneously
owns or has the right to acquire at no additional cost securities identical to
those sold short;

10. Purchase securities on margin, except that the fund may obtain such
short-term credits as may be necessary for the clearance of purchases and sales
of securities;

11. Borrow money, except from banks for temporary or emergency purposes not in
excess of 5% of the value of the fund's total assets, except that the fund may
enter into reverse repurchase agreements, provided that the fund will limit its
aggregate borrowings to no more than one-third of its total assets;

12. Mortgage, pledge, or hypothecate any of its assets, provided that this
restriction shall not apply to the sale of securities pursuant to a reverse
repurchase agreement;

13. Purchase or retain the securities of any issuer, if those individual
officers and Trustees of the Trust, its investment adviser, or distributor, each
owning beneficially more than 1/2 of 1% of the securities of such issuer,
together own more than 5% of the securities of such issuer;

14. Invest in interests in oil, gas, or other mineral exploration or
development programs;

15. Invest more than 5% of its total assets in warrants which are unattached to
securities;

16. Write, purchase or sell puts, calls or combinations thereof.

Notwithstanding Investment Restriction #4, the fund may invest in securities of
other investment companies if deemed advisable by its officers in connection
with the administration of a deferred compensation plan adopted by the Trustees
pursuant to an exemptive order granted by the Securities and Exchange
Commission. For purposes of Investment Restriction #6, the fund will not invest
more than 15% of its net assets in illiquid securities.

NONFUNDAMENTAL POLICY -- The following policy may be changed without shareholder
approval.

The fund may not issue senior securities, except as permitted by the 1940 Act.

TRUSTEE COMPENSATION -- No compensation is paid by the fund to any officer or
trustee who is a director, officer or employee of the investment adviser or its
affiliates. The boards of funds advised by the investment adviser typically meet
either individually or jointly with the boards of one or more other such funds
with substantially overlapping board membership (in each case referred to as a
"board cluster"). The fund typically pays each independent trustee an annual
fee, which ranges from $3,000 to $5,240, based primarily on the total number of
board clusters on which that independent trustee serves.

In addition, the fund generally pays independent trustees attendance and other
fees for meetings of the board and its committees. Board and committee chairs
receive additional fees for their services.

Independent trustees also receive attendance fees for certain special joint
meetings and information sessions with directors and trustees of other groupings
of funds advised by the investment adviser. The fund and the other funds served
by each independent trustee each pay an equal portion of these attendance fees.

U.S. Government Securities Fund -- Page 11
<PAGE>

No pension or retirement benefits are accrued as part of fund expenses.
Independent trustees may elect, on a voluntary basis, to defer all or a portion
of their fees through a deferred compensation plan in effect for the fund. The
fund also reimburses certain expenses of the independent trustees.

/1/ Amounts may be deferred by eligible trustees under a nonqualified deferred
compensation plan adopted by the fund in 1993. Deferred amounts accumulate at
an earnings rate determined by the total return of one or more American Funds
as designated by the trustees. Compensation shown in this table for the fiscal
year ended August 31, 2006 does not include earnings on amounts deferred in
previous fiscal years. See footnote 3 to this table for more information.
/2/ Funds managed by Capital Research and Management Company, including the
American Funds, American Funds Insurance Series,(R) which serves as the
underlying investment vehicle for certain variable insurance contracts, and
Endowments, whose shareholders are limited to certain nonprofit organizations.
/3/ Since the deferred compensation plan's adoption, the total amount of deferred
compensation accrued by the fund (plus earnings thereon) through the 2006
fiscal year for participating trustees is as follows: Richard G. Capen, Jr.
($33,894), H. Frederick Christie ($18,241), Diane C. Creel ($33,086), Martin
Fenton, ($37,489) and Leonard R. Fuller ($37,230). Amounts deferred and
accumulated earnings thereon are not funded and are general unsecured
liabilities of the fund until paid to the trustees.

As of October 1, 2006, the officers and trustees of the fund and their families,
as a group, owned beneficially or of record less than 1% of the outstanding
shares of the fund.

FUND ORGANIZATION AND THE BOARD OF TRUSTEES -- The fund, an open-end,
diversified management investment company, was organized as a Massachusetts
business trust on May 8,

U.S. Government Securities Fund -- Page 12
<PAGE>

1985. Although the board of trustees has delegated day-to-day oversight to the
investment adviser, all fund operations are supervised by the fund's board,
which meets periodically and performs duties required by applicable state and
federal laws.

Massachusetts common law provides that a trustee of a Massachusetts business
trust owes a fiduciary duty to the trust and must carry out his or her
responsibilities as a trustee in accordance with that fiduciary duty. Generally,
a trustee will satisfy his or her duties if he or she acts in good faith and
uses ordinary prudence.

Members of the board who are not employed by the investment adviser or its
affiliates are paid certain fees for services rendered to the fund as described
above. They may elect to defer all or a portion of these fees through a deferred
compensation plan in effect for the fund.

The fund has several different classes of shares, consisting of Class A, B, C,
F, 529-A, 529-B, 529-C, 529-E, 529-F, R-1, R-2, R-3, R-4 and R-5 shares. Shares
of each class represent an interest in the same investment portfolio. Each class
has pro rata rights as to voting, redemption, dividends and liquidation, except
that each class bears different distribution expenses and may bear different
transfer agent fees and other expenses properly attributable to the particular
class as approved by the board of trustees and set forth in the fund's rule
18f-3 Plan. Each class' shareholders have exclusive voting rights with respect
to the respective class' rule 12b-1 plans adopted in connection with the
distribution of shares and on other matters in which the interests of one class
are different from interests in another class. Shares of all classes of the fund
vote together on matters that affect all classes in substantially the same
manner. Each class votes as a class on matters that affect that class alone.
Note that CollegeAmerica/(R)/ account owners invested in Class 529 shares are
not shareholders of the fund and, accordingly, do not have the rights of a
shareholder, such as the right to vote proxies relating to fund shares. As the
legal owner of the fund's Class 529 shares, the Virginia College Savings
Plan/SM/ will vote any proxies relating to such fund shares.

The fund does not hold annual meetings of shareholders. However, significant
matters that require shareholder approval, such as certain elections of board
members or a change in a fundamental investment policy, will be presented to
shareholders at a meeting called for such purpose. Shareholders have one vote
per share owned. At the request of the holders of at least 10% of the shares,
the fund will hold a meeting at which any member of the board could be removed
by a majority vote.

REMOVAL OF TRUSTEES BY SHAREHOLDERS -- At any meeting of shareholders, duly
called and at which a quorum is present, shareholders may, by the affirmative
vote of the holders of a majority of the votes entitled to be cast, remove any
trustee from office and may elect a successor or successors to fill any
resulting vacancies for the unexpired terms of removed trustees. The fund has
agreed, at the request of the staff of the Securities and Exchange Commission,
to apply the provisions of section 16(c) of the 1940 Act with respect to the
removal of trustees, as though the fund were a common-law trust. Accordingly,
the trustees of the fund will promptly call a meeting of shareholders for the
purpose of voting upon the removal of any trustees when requested in writing to
do so by the record holders of at least 10% of the outstanding shares.

COMMITTEES OF THE BOARD OF TRUSTEES -- The fund has an audit committee comprised
of Diane C. Creel, Martin Fenton, Richard G. Newman and Frank M. Sanchez, none
of whom is an "interested person" of the fund within the meaning of the 1940
Act. The committee provides oversight regarding the fund's accounting and
financial reporting policies and practices, its

U.S. Government Securities Fund -- Page 13
<PAGE>

internal controls and the internal controls of the fund's principal service
providers. The committee acts as a liaison between the fund's independent
registered public accounting firm and the full board of trustees. Four audit
committee meetings were held during the 2006 fiscal year.

The fund has a contracts committee comprised of Richard G. Capen, Jr.; H.
Frederick Christie; Diane C. Creel; Martin Fenton; Leonard R. Fuller; R. Clark
Hooper; Richard G. Newman; and Frank M. Sanchez, none of whom is an "interested
person" of the fund within the meaning of the 1940 Act. The committee's
principal function is to request, review and consider the information deemed
necessary to evaluate the terms of certain agreements between the fund and its
investment adviser or the investment adviser's affiliates, such as the
Investment Advisory and Service Agreement, Principal Underwriting Agreement,
Administrative Services Agreement and Plans of Distribution adopted pursuant to
rule 12b-1 under the 1940 Act, that the fund may enter into, renew or continue,
and to make its recommendations to the full board of trustees on these matters.
One contracts committee meeting was held during the 2006 fiscal year.

The fund has a nominating and governance committee comprised of Richard G.
Capen, Jr., H. Frederick Christie, Diane C. Creel, Martin Fenton, Leonard R.
Fuller, R. Clark Hooper, Richard G. Newman and Frank M. Sanchez, none of whom is
an "interested person" of the fund within the meaning of the 1940 Act. The
committee periodically reviews such issues as the board's composition,
responsibilities, committees, compensation and other relevant issues, and
recommends any appropriate changes to the full board of trustees. The committee
also evaluates, selects and nominates independent trustee candidates to the full
board of trustees. While the committee normally is able to identify from its own
and other resources an ample number of qualified candidates, it will consider
shareholder suggestions of persons to be considered as nominees to fill future
vacancies on the board. Such suggestions must be sent in writing to the
nominating and governance committee of the fund, addressed to the fund's
secretary, and must be accompanied by complete biographical and occupational
data on the prospective nominee, along with a written consent of the prospective
nominee for consideration of his or her name by the committee. Three nominating
and governance committee meetings were held during the 2006 fiscal year.

PROXY VOTING PROCEDURES AND GUIDELINES -- The fund and its investment adviser
have adopted Proxy Voting Guidelines (the "Guidelines") with respect to voting
proxies of securities held by the fund, other American Funds, Endowments and
American Funds Insurance Series. Certain American Funds have established
separate proxy committees that vote proxies or delegate to a voting officer the
authority to vote on behalf of those funds. Proxies for all other funds are
voted by a committee of the investment adviser under authority delegated by
those funds' boards. Therefore, if more than one fund invests in the same
company, they may vote differently on the same proposal.

All U.S. proxies are voted. Non-U.S. proxies also are voted, provided there is
sufficient time and information available. After a proxy is received, the
investment adviser prepares a summary of the proposals in the proxy. A
discussion of any potential conflicts of interest is also included in the
summary. After reviewing the summary, one or more research analysts familiar
with the company and industry make a voting recommendation on the proxy
proposals. A second recommendation is made by a proxy coordinator (a senior
investment professional) based on the individual's knowledge of the Guidelines
and familiarity with proxy-related issues. The proxy summary and voting
recommendations are then sent to the appropriate proxy voting committee for the
final voting decision.

U.S. Government Securities Fund -- Page 14
<PAGE>

The analyst and proxy coordinator making voting recommendations are responsible
for noting any potential material conflicts of interest. One example might be
where a director of one or more American Funds is also a director of a company
whose proxy is being voted. In such instances, proxy committee members are
alerted to the potential conflict. The proxy committee may then elect to vote
the proxy or seek a third-party recommendation or vote of an ad hoc group of
committee members.

The Guidelines, which have been in effect in substantially their current form
for many years, provide an important framework for analysis and decision-making
by all funds. However, they are not exhaustive and do not address all potential
issues. The Guidelines provide a certain amount of flexibility so that all
relevant facts and circumstances can be considered in connection with every
vote. As a result, each proxy received is voted on a case-by-case basis
considering the specific circumstances of each proposal. The voting process
reflects the funds' understanding of the company's business, its management and
its relationship with shareholders over time.

Information regarding how the fund voted proxies relating to portfolio
securities during the 12-month period ended June 30 of each year will be
available on or about September 1 of each year (a) without charge, upon request
by calling American Funds Service Company at 800/421-0180, (b) on the American
Funds website at americanfunds.com and (c) on the SEC's website at sec.gov.

The following summary sets forth the general positions of the American Funds,
Endowments, American Funds Insurance Series and the investment adviser on
various proposals. A copy of the full Guidelines is available upon request, free
of charge, by calling American Funds Service Company at 800/421-0180 or visiting
the American Funds website.

DIRECTOR MATTERS -- The election of a company's slate of nominees for
director is generally supported. Votes may be withheld for some or all of
the nominees if this is determined to be in the best interest of
shareholders. Separation of the chairman and CEO positions may also be
supported. Typically, proposals to declassify the board (elect all
directors annually) are supported based on the belief that this increases
the directors' sense of accountability to shareholders.

SHAREHOLDER RIGHTS -- Proposals to repeal an existing poison pill, to
provide for confidential voting and to provide for cumulative voting are
usually supported. Proposals to eliminate the right of shareholders to act
by written consent or to take away a shareholder's right to call a special
meeting are not typically supported.

COMPENSATION AND BENEFIT PLANS -- Option plans are complicated, and many
factors are considered in evaluating a plan. Each plan is evaluated based
on protecting shareholder interests and a knowledge of the company and its
management. Considerations include the pricing (or repricing) of options
awarded under the plan and the impact of dilution on existing shareholders
from past and future equity awards. Compensation packages should be
structured to attract, motivate and retain existing employees and qualified
directors; however, they should not be excessive.

ROUTINE MATTERS -- The ratification of auditors, procedural matters
relating to the annual meeting and changes to company name are examples of
items considered routine. Such items are generally voted in favor of
management's recommendations unless circumstances indicate otherwise.

INVESTMENT ADVISER -- Capital Research and Management Company, the fund's
investment adviser, founded in 1931, maintains research facilities in the United
States and abroad (Los Angeles, San Francisco, New York, Washington, DC, London,
Geneva, Hong Kong, Singapore and Tokyo). These facilities are staffed with
experienced investment professionals. The investment adviser is located at 333
South Hope Street, Los Angeles, CA 90071 and 135 South State College Boulevard,
Brea, CA 92821. It is a wholly owned subsidiary of The Capital Group Companies,
Inc., a holding company for several investment management subsidiaries. The
investment adviser manages equity assets for the American Funds through two
divisions. These divisions generally function separately from each other with
respect to investment research activities and they make investment decisions for
the funds on a separate basis.

POTENTIAL CONFLICTS OF INTEREST -- The investment adviser has adopted policies
and procedures that address conflicts of interest that may arise between a
portfolio counselor's management of the fund and his or her management of other
funds and accounts. Potential areas of conflict could involve allocation of
investment opportunities and trades among funds and accounts, use of information
regarding the timing of fund trades, personal investing activities, portfolio
counselor compensation and voting relating to portfolio securities. The
investment adviser has adopted policies and procedures that it believes are
reasonably designed to address these conflicts. However, there is no guarantee
that such policies and procedures will be effective or that the investment
adviser will anticipate all potential conflicts of interest.

COMPENSATION OF INVESTMENT PROFESSIONALS -- As described in the prospectus, the
investment adviser uses a system of multiple portfolio counselors in managing
fund assets. In addition, Capital Research and Management Company's investment
analysts may make investment decisions with respect to a portion of a fund's
portfolio within their research coverage. Portfolio counselors and investment
analysts may also make investment decisions for other mutual funds advised by
Capital Research and Management Company.

Portfolio counselors and investment analysts are paid competitive salaries by
Capital Research and Management Company. In addition, they may receive bonuses
based on their individual portfolio results. Investment professionals also may
participate in profit-sharing plans. The relative mix of compensation
represented by bonuses, salary and profit-sharing will vary depending on the
individual's portfolio results, contributions to the organization and other
factors. In order to encourage a long-term focus, bonuses based on investment
results are calculated by comparing pretax total returns to relevant benchmarks
over both the most recent year and a four-year rolling average, with the greater
weight placed on the four-year rolling average. For portfolio counselors,
benchmarks may include measures of the marketplaces in which the relevant fund
invests and measures of the results of comparable mutual funds. For investment
analysts, benchmarks may include relevant market measures and appropriate
industry or sector indexes reflecting their areas of expertise. Capital Research
and Management Company also separately compensates analysts for the quality of
their research efforts. The benchmarks against which U.S. Government Securities
Fund portfolio counselors are measured include: Citigroup Treasury/ Government
Sponsored/Mortgage Index.

PORTFOLIO COUNSELOR FUND HOLDINGS AND OTHER MANAGED ACCOUNTS -- As described
below, portfolio counselors may personally own shares of the fund. In addition,
portfolio counselors may manage portions of other mutual funds or accounts
advised by Capital Research and Management Company or its affiliates.

INVESTMENT ADVISORY AND SERVICE AGREEMENT -- The Investment Advisory and Service
Agreement (the "Agreement") between the fund and the investment adviser will
continue in effect until May 31, 2007, unless sooner terminated, and may be
renewed from year to year thereafter, provided that any such renewal has been
specifically approved at least annually by (a) the board of trustees, or by the
vote of a majority (as defined in the 1940 Act) of the outstanding voting
securities of the fund, and (b) the vote of a majority of trustees who are not
parties to the Agreement or interested persons (as defined in the 1940 Act) of
any such party, cast in person at a meeting called for the purpose of voting on
such approval. The Agreement provides that the investment adviser has no
liability to the fund for its acts or omissions in the performance of its
obligations to the fund not involving willful misconduct, bad faith, gross
negligence or reckless disregard of its obligations under the Agreement. The
Agreement also provides that either party has the right to terminate it, without
penalty, upon 60 days' written notice to the other party, and that the Agreement
automatically terminates in the event of its assignment (as defined in the 1940
Act).

U.S. Government Securities Fund -- Page 18
<PAGE>

In addition to providing investment advisory services, the investment adviser
furnishes the services and pays the compensation and travel expenses of persons
to perform the fund's executive, administrative, clerical and bookkeeping
functions, and provides suitable office space, necessary small office equipment
and utilities, general purpose accounting forms, supplies and postage used at
the fund's offices. The fund pays all expenses not assumed by the investment
adviser, including, but not limited to, custodian, stock transfer and dividend
disbursing fees and expenses; shareholder recordkeeping and administrative
expenses; costs of the designing, printing and mailing of reports, prospectuses,
proxy statements and notices to its shareholders; taxes; expenses of the
issuance and redemption of fund shares (including stock certificates,
registration and qualification fees and expenses); expenses pursuant to the
fund's plans of distribution (described below); legal and auditing expenses;
compensation, fees and expenses paid to independent trustees; association dues;
costs of stationery and forms prepared exclusively for the fund; and costs of
assembling and storing shareholder account data.

The management fee is based upon the daily net assets of the fund and monthly
gross investment income. Gross investment income is determined in accordance
with generally accepted accounting principles and does not include gains or
losses from sales of capital assets.

The management fee is based on the following annualized rates and daily net
asset levels:

Net asset level

------------------------------------------------------------------------------

0.30% $ 0 $ 60,000,000

------------------------------------------------------------------------------
0.15 3,000,000,000
------------------------------------------------------------------------------

The Agreement also provides for fees based on monthly gross investment income at
the following annualized rates:

Monthly gross investment income

-----------------------------------------------------------------------------------
2.00 8,333,333
-----------------------------------------------------------------------------------

The investment adviser has agreed that in the event the Class A expenses of the
fund (with the exclusion of interest, taxes, brokerage costs, distribution
expenses pursuant to a plan under rule 12b-1 and extraordinary expenses such as
litigation and acquisitions or other expenses excludable under applicable state
securities laws or regulations) for any fiscal year ending on a date on which
the Agreement is in effect exceed the expense limitations, if any, applicable to
the fund pursuant to state securities laws or any related regulations, it will
reduce its fee by the extent of such excess and, if required pursuant to any
such laws or any regulations thereunder, will

U.S. Government Securities Fund -- Page 19
<PAGE>

reimburse the fund in the amount of such excess. To the extent the fund's
management fee must be waived due to Class A share expense ratios exceeding the
above limit, management fees will be reduced similarly for all classes of shares
of the fund, or other Class A fees will be waived in lieu of management fees.

For the fiscal years ended August 31, 2006 and 2005, the investment adviser was
entitled to receive from the fund management fees of $7,351,000 and $7,212,000,
respectively. After giving effect to the management fee waivers/expense
reimbursements described below, the fund paid the investment adviser management
fees of $6,616,000 (a reduction of $735,000) and $6,699,000 (a reduction of
$513,000) for the fiscal years ended August 31, 2006 and 2005, respectively. For
the fiscal year ended August 31, 2004, the fund paid the investment adviser
management fees of $7,534,000.

For the period from September 1, 2004 through March 31, 2005, the investment
adviser agreed to waive 5% of the management fees that it was otherwise entitled
to receive under the Agreement. Beginning April 1, 2005, this waiver increased
to 10% of the management fees that the investment adviser is otherwise entitled
to receive and this waiver is expected to continue at this level until further
review. As a result of this waiver, management fees will be reduced similarly
for all classes of shares of the fund. As of August 31, 2006, management fees
were reduced by $735,000 as a result of this waiver.

ADMINISTRATIVE SERVICES AGREEMENT -- The Administrative Services Agreement (the
"Administrative Agreement") between the fund and the investment adviser relating
to the fund's Class C, F, R and 529 shares will continue in effect until May 31,
2007, unless sooner terminated, and may be renewed from year to year thereafter,
provided that any such renewal has been specifically approved at least annually
by the vote of a majority of trustees who are not parties to the Administrative
Agreement or interested persons (as defined in the 1940 Act) of any such party,
cast in person at a meeting called for the purpose of voting on such approval.
The fund may terminate the Administrative Agreement at any time by vote of a
majority of independent trustees. The investment adviser has the right to
terminate the Administrative Agreement upon 60 days' written notice to the fund.
The Administrative Agreement automatically terminates in the event of its
assignment (as defined in the 1940 Act).

Under the Administrative Agreement, the investment adviser provides certain
transfer agent and administrative services for shareholders of the fund's Class
C and F shares, and all Class R and 529 shares. The investment adviser may contract
with third parties, including American Funds Service Company, the fund's
Transfer Agent, to provide these services. Services include, but are not limited
to, shareholder account maintenance, transaction processing, tax information
reporting and shareholder and fund communications. In addition, the investment
adviser monitors, coordinates and oversees the activities performed by third
parties providing such services. For Class R-1, Class R-2 and Class R-3 shares,
the investment adviser has agreed to pay a portion of the fees payable under the
Administrative Agreement that would otherwise have been paid by the fund. For
the year ended August 31, 2006, the total fees paid by the investment adviser
were $452,000.

The investment adviser receives an administrative services fee at the annual
rate of up to 0.15% of the average daily net assets for Class C, F, R (excluding
Class R-5 shares) and 529 shares for administrative services provided to these
share classes. Administrative services fees are paid monthly and accrued daily.
The investment adviser uses a portion of this fee to compensate third parties
for administrative services provided to the fund. Of the remainder, the
investment adviser does not retain more than 0.05% of the average daily net
assets for each applicable share class. For Class R-5 shares, the administrative
services fee is calculated at the annual rate of up to 0.10% of the average
daily net assets. The administrative services fee includes compensation for
transfer agent and shareholder services provided to the fund's Class C, F, R and
529 shares. In addition to making administrative service fee payments to
unaffiliated third parties, the investment adviser also makes payments from the
administrative services fee to American Funds Service Company according
to a fee schedule contained in a Shareholder Services Agreement between the fund
and American Funds Service Company.

PRINCIPAL UNDERWRITER AND PLANS OF DISTRIBUTION -- American Funds Distributors,

The fund has adopted plans of distribution (the "Plans") pursuant to rule 12b-1
under the 1940 Act. The Principal Underwriter receives amounts payable pursuant
to the Plans (see below). As required by rule 12b-1 and the 1940 Act, the Plans
(together with the Principal Underwriting Agreement) have been approved by the
full board of trustees and separately by a majority of the independent trustees
of the fund who have no direct or indirect financial interest in the operation
of the Plans or the Principal Underwriting Agreement. Potential benefits of the
Plans to the fund include quality shareholder services; savings to the fund in
transfer agency costs; and benefits to the investment process from growth or
stability of assets. The selection and nomination of independent trustees are
committed to the discretion of the independent trustees during the existence of
the Plans. The Plans may not be amended to increase materially the amount spent
for distribution without shareholder approval. Plan expenses are reviewed
quarterly and the Plans must be renewed annually by the board of trustees.

Under the Plans, the fund may annually expend the following amounts to finance
any activity primarily intended to result in the sale of fund shares, provided
the fund's board of trustees has approved the category of expenses for which
payment is being made: (a) for Class A shares, up to 0.30% of the average daily
net assets attributable to Class A shares; (b) for Class 529-A shares, up to
0.50% of the average daily net assets attributable to Class 529-A shares; (c)
for Class B and 529-B shares, up to 1.00% of the average daily net assets
attributable to Class B and 529-B shares, respectively; (d) for Class C and
529-C shares, up to 1.00% of the average daily net assets attributable to Class
C and 529-C shares, respectively; (e) for Class 529-E shares, up to 0.75% of the
average daily net assets attributable to Class 529-E shares; (f) for Class F and
529-F shares, up to 0.50% of the average daily net assets attributable to Class
F and 529-F shares, respectively; (g) for Class R-1 shares, up to 1.00% of the
average daily net assets attributable to Class R-1 shares; (h) for Class R-2
shares, up to 1.00% of the average daily net assets attributable to Class R-2
shares; (i) for Class R-3 shares, up to 0.75% of the average daily net assets
attributable to Class R-3 shares; and (j) for Class R-4 shares, up to 0.50% of
the average daily net assets attributable to Class R-4 shares. The fund has not
adopted a Plan for Class R-5 shares; accordingly, no 12b-1 fees are paid from
Class R-5 share assets.

For Class A and 529-A shares: (a) up to 0.25% is reimbursed to the Principal
Underwriter for paying service-related expenses, including paying service fees
to qualified dealers, and (b) up to the amount allowable under the fund's Class
A and 529-A 12b-1 limit is reimbursed to the Principal Underwriter for paying
distribution-related expenses, including for Class A and 529-A shares dealer
commissions and wholesaler compensation paid on sales of shares of $1 million or
more purchased without a sales charge (including purchases by employer-sponsored
defined contribution-type retirement plans investing $1 million or more or with
100 or more eligible employees, and retirement plans, endowments and foundations
with $50 million or more in assets -- "no load purchases"). Commissions on no
load purchases of Class A and 529-A shares in excess of the Class A and 529-A
plan limitations not reimbursed to the Principal Underwriter during the most
recent fiscal quarter are recoverable for five quarters, provided that such
commissions do not exceed the annual expense limit. After five quarters, these
commissions are not recoverable.

For Class B and 529-B shares: (a) up to 0.25% is paid to the Principal
Underwriter for paying service-related expenses, including paying service fees
to qualified dealers, and (b) 0.75% is paid to the Principal Underwriter for
distribution-related expenses, including the financing of commissions paid to
qualified dealers.

EXECUTION OF PORTFOLIO TRANSACTIONS

As described in the prospectus, the investment adviser places orders with
broker-dealers for the fund's portfolio transactions. Portfolio transactions for
the fund may be executed as part of concurrent authorizations to purchase or
sell the same security for other funds served by the investment adviser, or for
trusts or other accounts served by affiliated companies of the investment
adviser. When such concurrent authorizations occur, the objective is to allocate
the executions in an equitable manner.

Brokerage commissions paid on portfolio transactions, including investment
dealer concessions on underwritings, if applicable, for the fiscal years ended
August 31, 2006, 2005 and 2004 amounted to $227,000, $11,000 and $0,
respectively. With respect to fixed-income securities, brokerage commissions
include explicit investment dealer concessions and may exclude other transaction
costs which may be reflected in the spread between the bid and asked price. The
volume of securities purchased by the fund in underwritten offerings increased
from the previous year, resulting in an increase in brokerage concessions paid
on portfolio transactions.

DISCLOSURE OF PORTFOLIO HOLDINGS

The fund's investment adviser, on behalf of the fund, has adopted policies and
procedures with respect to the disclosure of information about fund portfolio
securities. These policies and procedures have been reviewed by the fund's board
of trustees and compliance will be periodically assessed by the board in
connection with reporting from the fund's Chief Compliance Officer.

Under these policies and procedures, the fund's complete list of portfolio
holdings available for public disclosure, dated as of the end of each calendar
quarter, is permitted to be posted on the American Funds website no earlier than
the tenth day after such calendar quarter. In practice, the public portfolio
typically is posted on the website approximately 45 days after the end of the
calendar quarter. Such portfolio holdings information may then be disclosed to
any person pursuant to an ongoing arrangement to disclose portfolio holdings
information to such person no earlier than one day after the day on which the
information is posted on the American Funds website. The fund's custodian,
outside counsel and auditor, each of which require portfolio holdings
information for legitimate business and fund oversight purposes, may receive the
information earlier.

Affiliated persons of the fund as described above who receive portfolio holdings
information are subject to restrictions and limitations on the use and handling
of such information pursuant to applicable codes of ethics, including
requirements to maintain the confidentiality of such information, preclear
securities trades and report securities transactions activity, as applicable.
Third party service providers of the fund receiving such information are subject
to confidentiality obligations. When portfolio holdings information is disclosed
other than through the American Funds website to persons not affiliated with the
fund (which, as described above, would typically occur no earlier than one day
after the day on which the information is posted on the American Funds website),
such persons may be bound by agreements (including confidentiality agreements)
that restrict and limit their use of the information to legitimate business uses
only. Neither the fund nor its investment adviser or any affiliate thereof
receives compensation or other consideration in connection with the disclosure
of information about portfolio securities.

U.S. Government Securities Fund -- Page 27
<PAGE>

Subject to board policies, the authority to disclose a fund's portfolio
holdings, and to establish policies with respect to such disclosure, resides
with the appropriate investment-related committees of the fund's investment
adviser. In exercising their authority, the committees determine whether
disclosure of information about the fund's portfolio securities is appropriate
and in the best interest of fund shareholders. The investment adviser has
implemented policies and procedures to address conflicts of interest that may
arise from the disclosure of fund holdings. For example, the investment
adviser's code of ethics specifically requires, among other things, the
safeguarding of information about fund holdings and contains prohibitions
designed to prevent the personal use of confidential, proprietary investment
information in a way that would conflict with fund transactions. In addition,
the investment adviser believes that its current policy of not selling portfolio
holdings information and not disclosing such information to unaffiliated third
parties until such holdings have been made public on the American Funds website
(other than to certain fund service providers for legitimate business and fund
oversight purposes) helps reduce potential conflicts of interest between fund
shareholders and the investment adviser and its affiliates.

PRICE OF SHARES

Shares are purchased at the offering price or sold at the net asset value price
next determined after the purchase or sell order is received and accepted by the
fund or the Transfer Agent; the offering or net asset value price is effective
for orders received prior to the time of determination of the net asset value
and, in the case of orders placed with dealers or their authorized designees,
accepted by the Principal Underwriter, the Transfer Agent, a dealer or any of
their designees. In the case of orders sent directly to the fund or the Transfer
Agent, an investment dealer should be indicated. The dealer is responsible for
promptly transmitting purchase and sell orders to the Principal Underwriter.

Orders received by the investment dealer or authorized designee, the Transfer
Agent or the fund after the time of the determination of the net asset value
will be entered at the next calculated offering price. Note that investment
dealers or other intermediaries may have their own rules about share
transactions and may have earlier cut-off times than those of the fund. For more
information about how to purchase through your intermediary, contact your
intermediary directly.

Prices that appear in the newspaper do not always indicate prices at which you
will be purchasing and redeeming shares of the fund, since such prices generally
reflect the previous day's closing price, while purchases and redemptions are
made at the next calculated price. The price you pay for shares, the offering
price, is based on the net asset value per share, which is calculated once daily
as of approximately 4:00 p.m. New York time, which is the normal close of
trading on the New York Stock Exchange, each day the Exchange is open. If, for
example, the Exchange closes at 1:00 p.m., the fund's share price would still be
determined as of 4:00 p.m. New York time. The New York Stock Exchange is
currently closed on weekends and on the following holidays: New Year's Day;
Martin Luther King, Jr. Day; Presidents' Day; Good Friday; Memorial Day;
Independence Day; Labor Day; Thanksgiving; and Christmas Day. Each share class
of the fund has a separately calculated net asset value (and share price).

All portfolio securities of funds managed by Capital Research and Management
Company (other than money market funds) are valued, and the net asset values per
share for each share class are determined, as follows:

U.S. Government Securities Fund -- Page 28
<PAGE>

1. Equity securities, including depositary receipts, are valued at the
official closing price of, or the last reported sale price on, the exchange or
market on which such securities are traded, as of the close of business on the
day the securities are being valued or, lacking any sales, at the last available
bid price. Prices for each security are taken from the principal exchange or
market in which the security trades. Fixed-income securities are valued at
prices obtained from an independent pricing service, when such prices are
available; however, in circumstances where the investment adviser deems it
appropriate to do so, such securities will be valued at the mean quoted bid and
asked prices (or bid prices, if asked prices are not available) or at prices for
securities of comparable maturity, quality and type. The pricing services base
bond prices on, among other things, an evaluation of the yield curve as of
approximately 3:00 p.m. New York time. The fund's investment adviser performs
certain checks on these prices prior to calculation of the fund's net asset
value.

Securities with both fixed-income and equity characteristics (e.g., convertible
bonds, preferred stocks, units comprised of more than one type of security,
etc.), or equity securities traded principally among fixed-income dealers, are
valued in the manner described above for either equity or fixed-income
securities, depending on which method is deemed most appropriate by the
investment adviser.

Securities with original maturities of one year or less having 60 days or less
to maturity are amortized to maturity based on their cost if acquired within 60
days of maturity, or if already held on the 60th day, based on the value
determined on the 61st day. Forward currency contracts are valued at the mean of
representative quoted bid and asked prices.

Assets or liabilities initially expressed in terms of non-U.S. currencies are
translated prior to the next determination of the net asset value of the fund's
shares into U.S. dollars at the prevailing market rates.

Securities and assets for which market quotations are not readily available or
are considered unreliable are valued at fair value as determined in good faith
under policies approved by the fund's board. Subject to board oversight, the
fund's board has delegated the obligation to make fair valuation determinations
to a valuation committee established by the fund's investment adviser. The board
receives regular reports describing fair-valued securities and the valuation
methods used.

The valuation committee has adopted guidelines and procedures (consistent with
SEC rules and guidance) to ensure that certain basic principles and factors are
considered when making all fair value determinations. As a general principle,
securities lacking readily available market quotations, or that have quotations
that are considered unreliable by the investment adviser, are valued in good
faith by the valuation committee based upon what the fund might reasonably
expect to receive upon their current sale. The valuation committee considers all
indications of value available to it in determining the fair value to be
assigned to a particular security, including, without limitation, the type and
cost of the security, contractual or legal restrictions on resale of the
security, relevant financial or business developments of the issuer, actively
traded similar or related securities, conversion or exchange rights on the
security, related corporate actions, significant events occurring after the
close of trading in the security and changes in overall market conditions. The
fund follows standard industry practice by typically reflecting changes in its
holdings of portfolio securities on the first business day following a portfolio
trade.

U.S. Government Securities Fund -- Page 29
<PAGE>

2. Each class of shares represents interests in the same portfolio of
investments and is identical in all respects to each other class, except for
differences relating to distribution, service and other charges and expenses,
certain voting rights, differences relating to eligible investors, the
designation of each class of shares, conversion features and exchange
privileges. Expenses attributable to the fund, but not to a particular class of
shares, are borne by each class pro rata based on relative aggregate net assets
of the classes. Expenses directly attributable to a class of shares are borne by
that class of shares. Liabilities, including accruals of taxes and other expense
items attributable to particular share classes, are deducted from total assets
attributable to such share classes.

3. Net assets so obtained for each share class are then divided by the total
number of shares outstanding of that share class, and the result, rounded to the
nearer cent, is the net asset value per share for that share class.

TAXES AND DISTRIBUTIONS

FUND TAXATION -- The fund has elected to be treated as a regulated investment
company under Subchapter M of the Internal Revenue Code (the "Code"). A
regulated investment company qualifying under Subchapter M of the Code is
required to distribute to its shareholders at least 90% of its investment
company taxable income (including the excess of net short-term capital gain over
net long-term capital losses) and generally is not subject to federal income tax
to the extent that it distributes annually 100% of its investment company
taxable income and net realized capital gains in the manner required under the
Code. The fund intends to distribute annually all of its investment company
taxable income and net realized capital gains and therefore does not expect to
pay federal income tax, although in certain circumstances, the fund may
determine that it is in the interest of shareholders to distribute less than
that amount.

To be treated as a regulated investment company under Subchapter M of the Code,
the fund must also (a) derive at least 90% of its gross income from dividends,
interest, payments with respect to securities loans, net income from certain
publicly traded partnerships and gains from the sale or other disposition of
securities or foreign currencies, or other income (including, but not limited
to, gains from options, futures or forward contracts) derived with respect to
the business of investing in such securities or currencies, and (b) diversify
its holdings so that, at the end of each fiscal quarter, (i) at least 50% of the
market value of the fund's assets is represented by cash, U.S. government
securities and securities of other regulated investment companies, and other
securities (for purposes of this calculation, generally limited in respect of
any one issuer, to an amount not greater than 5% of the market value of the
fund's assets and 10% of the outstanding voting securities of such issuer) and
(ii) not more than 25% of the value of its assets is invested in the securities
of (other than U.S. government securities or the securities of other regulated
investment companies) any one issuer; two or more issuers which the fund
controls and which are determined to be engaged in the same or similar trades or
businesses; or the securities of certain publicly traded partnerships.

Under the Code, a nondeductible excise tax of 4% is imposed on the excess of a
regulated investment company's "required distribution" for the calendar year
ending within the regulated investment company's taxable year over the
"distributed amount" for such calendar year. The term "required distribution"
means the sum of (a) 98% of ordinary income (generally net investment income)
for the calendar year, (b) 98% of capital gain (both long-term and short-term)
for the one-year period ending on October 31 (as though the one-year period
ending on October 31 were the regulated investment company's taxable year) and
(c) the sum of any untaxed,

U.S. Government Securities Fund -- Page 30
<PAGE>

undistributed net investment income and net capital gains of the regulated
investment company for prior periods. The term "distributed amount" generally
means the sum of (a) amounts actually distributed by the fund from its current
year's ordinary income and capital gain net income and (b) any amount on which
the fund pays income tax during the periods described above. Although the fund
intends to distribute its net investment income and net capital gains so as to
avoid excise tax liability, the fund may determine that it is in the interest of
shareholders to distribute a lesser amount. The fund may pass through the income
earned on certain U.S. government bonds free of various states' income taxes.
However, a few states require the fund to hold more than 50% of its assets in
these types of government bonds at the end of every fiscal quarter in order to
qualify for the tax exemption. The fund does not currently intend to actively
meet the 50% threshold in order to qualify for the tax exemption in those few
states.

The following information may not apply to you if you hold fund shares in a
tax-deferred account, such as a retirement plan or education savings account.
Please see your tax adviser for more information.

DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS -- Dividends and capital gain
distributions on fund shares will be reinvested in shares of the fund of the
same class, unless shareholders indicate in writing that they wish to receive
them in cash or in shares of the same class of other American Funds, as provided
in the prospectus. Dividends and capital gain distributions by 529 share classes
will be automatically reinvested.

Distributions of investment company taxable income and net realized capital
gains to shareholders will be taxable whether received in shares or in cash,
unless such shareholders are exempt from taxation. Shareholders electing to
receive distributions in the form of additional shares will have a cost basis
for federal income tax purposes in each share so received equal to the net asset
value of that share on the reinvestment date. Dividends and capital gain
distributions by the fund to a tax-deferred retirement plan account are not
taxable currently.

DIVIDENDS -- The fund intends to follow the practice of distributing
substantially all of its investment company taxable income. Investment
company taxable income generally includes dividends, interest, net
short-term capital gains in excess of net long-term capital losses, and
certain foreign currency gains, if any, less expenses and certain foreign
currency losses.

A portion of the difference between the issue price of zero coupon
securities and their face value (original issue discount) is considered to
be income to the fund each year, even though the fund will not receive cash
interest payments from these securities. This original issue discount
(imputed income) will comprise a part of the investment company taxable
income of the fund that must be distributed to shareholders in order to
maintain the qualification of the fund as a regulated investment company
and to avoid federal income taxation at the level of the fund.

The price of a bond purchased after its original issuance may reflect
market discount which, depending on the particular circumstances, may
affect the tax character and amount of income required to be recognized by
a fund holding the bond. In determining whether a bond is purchased with
market discount, certain de minimis rules apply.

CAPITAL GAIN DISTRIBUTIONS -- The fund also intends to follow the practice
of distributing the entire excess of net realized long-term capital gains
over net realized short-term

U.S. Government Securities Fund -- Page 31
<PAGE>

capital losses. Net capital gains for a fiscal year are computed by taking
into account any capital loss carry forward of the fund.

If any net long-term capital gains in excess of net short-term capital
losses are retained by the fund for reinvestment, requiring federal income
taxes to be paid thereon by the fund, the fund intends to elect to treat
such capital gains as having been distributed to shareholders. As a result,
each shareholder will report such capital gains as long-term capital gains
taxable to individual shareholders at a maximum 15% capital gains rate,
will be able to claim a pro rata share of federal income taxes paid by the
fund on such gains as a credit against personal federal income tax
liability, and will be entitled to increase the adjusted tax basis on fund
shares by the difference between a pro rata share of the retained gains and
such shareholder's related tax credit.

SHAREHOLDER TAXATION -- In January of each year, individual shareholders holding
fund shares in taxable accounts will receive a statement of the federal income
tax status of all distributions. Shareholders of the fund also may be subject to
state and local taxes on distributions received from the fund.

DIVIDENDS -- Fund dividends are taxable to shareholders as ordinary income.
Under the 2003 Tax Act, all or a portion of a fund's dividend distribution
may be a "qualified dividend." If the fund meets the applicable holding
period requirement, it will distribute dividends derived from qualified
corporation dividends to shareholders as qualified dividends. Interest
income from bonds and money market instruments and nonqualified foreign
dividends will be distributed to shareholders as nonqualified fund
dividends. The fund will report on Form 1099-DIV the amount of each
shareholder's dividend that may be treated as a qualified dividend. If a
shareholder meets the requisite holding period requirement, qualified
dividends are taxable at a maximum rate of 15%.

CAPITAL GAINS -- Distributions of the excess of net long-term capital gains
over net short-term capital losses that the fund properly designates as
"capital gain dividends" generally will be taxable as long-term capital
gain. Regardless of the length of time the shares of the fund have been
held by a shareholder, a capital gain distribution by the fund is subject
to a maximum tax rate of 15%. Any loss realized upon the redemption of
shares held at the time of redemption for six months or less from the date
of their purchase will be treated as a long-term capital loss to the extent
of any amounts treated as distributions of long-term capital gains during
such six-month period.

Distributions by the fund result in a reduction in the net asset value of the
fund's shares. Investors should consider the tax implications of buying shares
just prior to a distribution. The price of shares purchased at that time
includes the amount of the forthcoming distribution. Those purchasing just prior
to a distribution will subsequently receive a partial return of their investment
capital upon payment of the distribution, which will be taxable to them.

Redemptions of shares, including exchanges for shares of other American Funds,
may result in federal, state and local tax consequences (gain or loss) to the
shareholder.

If a shareholder exchanges or otherwise disposes of shares of the fund within 90
days of having acquired such shares, and if, as a result of having acquired
those shares, the shareholder subsequently pays a reduced sales charge for
shares of the fund, or of a different fund, the sales

U.S. Government Securities Fund -- Page 32
<PAGE>

charge previously incurred in acquiring the fund's shares will not be taken into
account (to the extent such previous sales charges do not exceed the reduction
in sales charges) for the purposes of determining the amount of gain or loss on
the exchange, but will be treated as having been incurred in the acquisition of
such other fund(s).

Any loss realized on a redemption or exchange of shares of the fund will be
disallowed to the extent substantially identical shares are reacquired within
the 61-day period beginning 30 days before and ending 30 days after the shares
are disposed of. Any loss disallowed under this rule will be added to the
shareholder's tax basis in the new shares purchased.

The fund will be required to report to the IRS all distributions of investment
company taxable income and capital gains as well as gross proceeds from the
redemption or exchange of fund shares, except in the case of certain exempt
shareholders. Under the backup withholding provisions of Section 3406 of the
Code, distributions of investment company taxable income and capital gains and
proceeds from the redemption or exchange of a regulated investment company may
be subject to backup withholding of federal income tax in the case of non-exempt
U.S. shareholders who fail to furnish the investment company with their taxpayer
identification numbers and with required certifications regarding their status
under the federal income tax law. Withholding may also be required if the fund
is notified by the IRS or a broker that the taxpayer identification number
furnished by the shareholder is incorrect or that the shareholder has previously
failed to report interest or dividend income. If the withholding provisions are
applicable, any such distributions and proceeds, whether taken in cash or
reinvested in additional shares, will be reduced by the amounts required to be
withheld.

The foregoing discussion of U.S. federal income tax law relates solely to the
application of that law to U.S. persons (i.e., U.S. citizens and residents and
U.S. corporations, partnerships, trusts and estates). Each shareholder who is
not a U.S. person should consider the U.S. and foreign tax consequences of
ownership of shares of the fund, including the possibility that such a
shareholder may be subject to a U.S. withholding tax at a rate of 30% (or a
lower rate under an applicable income tax treaty) on dividend income received by
the shareholder.

Shareholders should consult their tax advisers about the application of federal,
state and local tax law in light of their particular situation.

The Principal Underwriter will not knowingly sell shares of the fund directly or
indirectly to any person or entity, where, after the sale, such person or entity
would own beneficially directly or indirectly more than 4.5% of the outstanding
shares of the fund without the consent of a majority of the fund's board.

Class 529 shares may be purchased only through CollegeAmerica by investors
establishing qualified higher education savings accounts. Class 529-E shares may
be purchased only by investors participating in CollegeAmerica through an
eligible employer plan. Class R-5 shares are also available to clients of the
Personal Investment Management group of Capital Guardian Trust Company who do
not have an intermediary associated with their accounts and without regard to
the $1 million purchase minimum. In addition, the American Funds state
tax-exempt funds are qualified for sale only in certain jurisdictions, and
tax-exempt funds in general should not serve as retirement plan investments. The
fund and the Principal Underwriter reserve the right to reject any purchase
order.

PURCHASE MINIMUMS AND MAXIMUMS -- All investments are subject to the purchase
minimums and maximums described in the prospectus. As noted in the prospectus,
purchase minimums may be waived or reduced in certain cases.

In the case of American Funds non-tax-exempt funds, the initial purchase minimum
of $25 may be waived for the following account types:

. Payroll deduction retirement plan accounts (such as, but not limited
to, 403(b), 401(k), SIMPLE IRA, SARSEP and deferred compensation plan
accounts); and

. Employer-sponsored CollegeAmerica accounts.

The following account types may be established without meeting the initial
purchase minimum:

. Retirement accounts that are funded with employer contributions; and

. Accounts that are funded with monies set by court decree.

U.S. Government Securities Fund -- Page 35
<PAGE>

The following account types may be established without meeting the initial
purchase minimum, but shareholders wishing to invest in two or more funds must
meet the normal initial purchase minimum of each fund:

. Accounts that are funded with (a) transfers of assets, (b) rollovers
from retirement plans, (c) rollovers from 529 college savings plans or
(d) required minimum distribution automatic exchanges; and

. American Funds money market fund accounts registered in the name of
clients of Capital Guardian Trust Company's Personal Investment
Management group.

Certain accounts held on the fund's books, known as omnibus accounts, contain
multiple underlying accounts that are invested in shares of the fund. These
underlying accounts are maintained by entities such as financial intermediaries
and are subject to the applicable initial purchase minimums as described in the
prospectus and statement of additional information. However, in the case where
the entity maintaining these accounts aggregates the accounts' purchase orders
for fund shares, such accounts are not required to meet the minimum amount for
subsequent purchases.

EXCHANGES -- You may only exchange shares into other American Funds within the
same share class. However, exchanges from Class A shares of The Cash Management
Trust of America may be made to Class B or C shares of other American Funds for
dollar cost averaging purposes. Exchanges from Class A shares of The Cash
Management Trust of America to Class B or C shares of Intermediate Bond Fund of
America, Limited Term Tax-Exempt Bond Fund of America and Short-Term Bond Fund
of America are not permitted. Exchange purchases are subject to the minimum
investment requirements of the fund purchased and no sales charge generally
applies. However, exchanges of shares from American Funds money market funds are
subject to applicable sales charges on the fund being purchased, unless the
money market fund shares were acquired by an exchange from a fund having a sales
charge, or by reinvestment or cross-reinvestment of dividends or capital gain
distributions. Exchanges of Class F shares generally may only be made through
fee-based programs of investment firms that have special agreements with the
fund's distributor and certain registered investment advisers.

You may exchange shares of other classes by contacting the Transfer Agent, by
contacting your investment dealer or financial adviser, by using American
FundsLine or americanfunds.com, or by telephoning 800/421-0180 toll-free, or
faxing (see "American Funds Service Company service areas" in the prospectus for
the appropriate fax numbers) the Transfer Agent. For more information, see
"Shareholder account services and privileges" below. THESE TRANSACTIONS HAVE THE
SAME TAX CONSEQUENCES AS ORDINARY SALES AND PURCHASES.

Shares held in employer-sponsored retirement plans may be exchanged into other
American Funds by contacting your plan administrator or recordkeeper. Exchange
redemptions and purchases are processed simultaneously at the share prices next
determined after the exchange order is received (see "Price of shares" above).

FREQUENT TRADING OF FUND SHARES -- As noted in the prospectus, certain
redemptions may trigger a purchase block lasting 30 calendar days under the
fund's "purchase blocking policy." Under this policy, systematic redemptions
will not trigger a purchase block and systematic purchases will not be
prevented. For purposes of this policy, systematic redemptions include, for
example, regular periodic automatic redemptions and statement of intention
escrow share

U.S. Government Securities Fund -- Page 36
<PAGE>

redemptions. Systematic purchases include, for example, regular periodic
automatic purchases and automatic reinvestments of dividends and capital gain
distributions.

The fund, through its transfer agent, American Funds Service Company,
maintains surveillance procedures to detect frequent trading in fund
shares. Under these procedures, various analytics are used to evaluate
factors that may be indicative of frequent trading. For example,
transactions in fund shares that exceed certain monetary thresholds may be
scrutinized. American Funds Service Company also may review transactions
that occur close in time to other transactions in the same account or in
multiple accounts under common ownership or influence. Trading activity
that is identified through these procedures or as a result of any other
information available to the fund will be evaluated to determine whether
such activity might constitute frequent trading. These procedures may be
modified from time to time as appropriate to improve the detection of
frequent trading, to facilitate monitoring for frequent trading in
particular retirement plans or other accounts, and to comply with
applicable laws.

In addition to the fund's broad ability to restrict potentially harmful
trading, the fund's board of directors has adopted a "purchase blocking
policy," under which any shareholder redeeming shares (including
redemptions that are part of an exchange transaction) having a value of
$5,000 or more from the fund will be precluded from investing in
the fund (including investments that are part of an exchange transaction)
for 30 calendar days after the redemption transaction. Under the fund's
purchase blocking policy, certain purchases will not be prevented and
certain redemptions will not trigger a purchase block, such as: systematic
redemptions and purchases where the entity maintaining the shareholder
account is able to identify the transaction as a systematic redemption or
purchase; purchases and redemptions of shares having a value of less than
$5,000; transactions in Class 529 shares; purchases and redemptions
resulting from reallocations by American Funds Target Date Retirement
Series; retirement plan contributions, loans and distributions (including
hardship withdrawals) identified as such on the retirement plan
recordkeeper's system; and purchase transactions involving transfers of
assets, rollovers, Roth IRA conversions and IRA recharacterizations, where
the entity maintaining the shareholder account is able to identify the
transaction as one of these types of transactions.

The fund reserves the right to waive the purchase blocking policy in those
instances where American Funds Service Company determines that its
surveillance procedures are adequate to detect frequent trading in fund
shares.

American Funds Service Company will work with certain intermediaries (such
as investment dealers holding shareholder accounts in street name,
retirement plan recordkeepers, insurance company separate accounts and bank
trust companies) to apply their procedures which American Funds Service
Company believes are reasonably designed to enforce the frequent trading
policies of the fund. You should refer to disclosures provided by the
intermediaries with which you have an account to determine the specific
trading restrictions that apply to you.

If American Funds Service Company identifies any activity that may
constitute frequent trading, it reserves the right to contact the
intermediary and request that the intermediary either provide information
regarding an account owner's transactions or restrict the account owner's
trading. If American Funds Service Company is not satisfied that the
intermediary has taken appropriate action, American Funds Service Company
may terminate the intermediary's ability to transact in fund shares.

There is no guarantee that all instances of frequent trading in fund shares
will be prevented.

Notwithstanding the fund's surveillance procedures and purchase blocking
policy, all transactions in fund shares remain subject to the fund's and
American Funds Distributors' right to restrict potentially abusive trading
generally (including the types of transactions described above that will
not be prevented or trigger a block under the purchase blocking policy).

OTHER POTENTIALLY ABUSIVE ACTIVITY -- In addition to implementing purchase
blocks, American Funds Service Company will monitor for other types of activity
that could potentially be harmful to the American Funds - for example,
short-term trading activity in multiple funds. When identified, American Funds
Service Company will request that the shareholder discontinue the activity. If
the activity continues, American Funds Service Company will freeze the
shareholder account to prevent all activity other than redemptions of fund
shares.

MOVING BETWEEN SHARE CLASSES

AUTOMATIC CONVERSIONS -- As described more fully in the prospectus, Class
B, 529-B and C shares automatically convert to Class A, 529-A and F shares,
respectively, after a certain period from the purchase date.

MOVING FROM CLASS B TO CLASS A SHARES -- Under the right of reinvestment
policy as described in the prospectus, if you redeem Class B shares during
the contingent deferred sales charge period, you may reinvest the proceeds
in Class A shares without paying a Class A sales charge if you notify
American Funds Service Company and the reinvestment occurs within 90 days
after the date of redemption and is made into the same account from which
you redeemed the shares. If you redeem your Class B shares after the
contingent deferred sales charge period, you may either reinvest the
proceeds in Class B shares or purchase Class A shares. If you purchase
Class A shares, you are responsible for paying any applicable Class A sales
charges.

MOVING FROM CLASS C TO CLASS A SHARES -- If you redeem Class C shares and
with the redemption proceeds purchase Class A shares, you are still
responsible for paying any Class C contingent deferred sales charges and
applicable Class A sales charges.

MOVING FROM CLASS F TO CLASS A SHARES -- You can redeem Class F shares held
in a qualified fee-based program and with the redemption proceeds purchase
Class A shares without paying an initial Class A sales charge if all of the
following are met: (a) you are leaving or have left the fee-based program,
(b) you have held the Class F shares in the program for at least one year,
and (c) you notify American Funds Service Company and purchase the Class A
shares within 90 days after redeeming the Class F shares.

MOVING FROM CLASS A TO CLASS F SHARES -- If you are part of a qualified
fee-based program and you wish to redeem your Class A shares and with the
redemption proceeds purchase Class F shares for the program, any Class A
sales charges (including contingent deferred sales charges) that you paid
or are payable will not be credited back to your account.

MOVING FROM CLASS A TO CLASS R SHARES -- Provided it is eligible to invest
in Class R shares, a retirement plan currently invested in Class A shares
may redeem its shares and purchase Class R shares with the redemption
proceeds. Any Class A sales charges that the retirement plan previously
paid will not be credited back to the plan's account.

NON-REPORTABLE TRANSACTIONS -- As described above, automatic conversions
will be non-reportable for tax purposes. In addition, except in the case of
a movement between a 529 share class and a non-529 share class or vice
versa, an exchange of shares from one share class of a fund to another
share class of the same fund will be treated as a non-reportable exchange
for tax purposes, provided that the exchange request is received in writing
by American Funds Service Company and processed as a single transaction.

SALES CHARGES

CLASS A PURCHASES

PURCHASES BY CERTAIN 403(B) PLANS

Individual 403(b) plans may be treated similarly to employer-sponsored
plans for Class A sales charge purposes (i.e., individual participant
accounts are eligible to be aggregated together) if: (a) the American Funds
are principal investment options; (b) the employer facilitates the
enrollment process by, for example, allowing for onsite group enrollment
meetings held during working hours; and (c) there is only one dealer firm
assigned to the plans.

OTHER PURCHASES

Pursuant to a determination of eligibility by a vice president or more
senior officer of the Capital Research and Management Company Fund
Administration Unit, or by his or her designee, Class A shares of the
American Funds stock, stock/bond and bond funds may be sold at net asset
value to:

(1) current or retired directors, trustees, officers and advisory board
members of, and certain lawyers who provide services to, the funds
managed by Capital Research and Management Company, current or retired
employees of Washington Management Corporation, current or retired
employees and partners of The Capital Group Companies, Inc. and its
affiliated companies, certain family members and employees of the
above persons, and trusts or plans primarily for such persons;

(2) currently registered representatives and assistants directly employed
by such representatives, retired registered representatives with
respect to accounts established while active, or full-time employees
(collectively, "Eligible Persons") (and their (a) spouses or
equivalents if recognized under local law, (b) parents and children,
including parents and children in step and adoptive relationships,
sons-in-law and daughters-in-law, and (c) parents-in-law, if the
Eligible Persons or the spouses, children or parents of the Eligible
Persons are listed in the account registration with the
parents-in-law) of dealers who have sales agreements with the
Principal Underwriter (or who clear transactions through such
dealers), plans for the dealers, and plans that include as
participants only the Eligible Persons, their spouses, parents and/or
children;

(3) currently registered investment advisers ("RIAs") and assistants
directly employed by such RIAs, retired RIAs with respect to accounts
established while active, or full-time employees (collectively,
"Eligible Persons") (and their (a) spouses or equivalents if
recognized under local law, (b) parents and children, including
parents and children in step and adoptive relationships, sons-in-law
and daughters-in-law and (c) parents-in-law, if the Eligible Persons
or the spouses, children or parents of the Eligible Persons are listed
in the account registration with the parents-in-law) of RIA firms that
are authorized to sell shares of the funds, plans for the RIA firms,
and plans that include as participants only the Eligible Persons,
their spouses, parents and/or children;

U.S. Government Securities Fund -- Page 38
<PAGE>

(4) companies exchanging securities with the fund through a merger,
acquisition or exchange offer;

(5) insurance company separate accounts;

(6) accounts managed by subsidiaries of The Capital Group Companies, Inc.;

(7) The Capital Group Companies, Inc., its affiliated companies and
Washington Management Corporation;

(8) an individual or entity with a substantial business relationship with

whose underlying investments are managed by any affiliate of The
Capital Group Companies, Inc.; and

(10) full-time employees of banks that have sales agreements with the
Principal Underwriter, who are solely dedicated to directly supporting
the sale of mutual funds.

Shares are offered at net asset value to these persons and organizations
due to anticipated economies in sales effort and expense. Once an account
is established under this net asset value privilege, additional investments
can be made at net asset value for the life of the account.

MOVING BETWEEN ACCOUNTS -- Investments in certain account types may be moved to
other account types without incurring additional Class A sales charges. These
transactions include, for example:

. redemption proceeds from a non-retirement account (for example, a
joint tenant account) used to purchase fund shares in an IRA or other
individual-type retirement account;

. required minimum distributions from an IRA or other individual-type
retirement account used to purchase fund shares in a non-retirement
account; and

. death distributions paid to a beneficiary's account that are used by
the beneficiary to purchase fund shares in a different account.

LOAN REPAYMENTS -- Repayments on loans taken from a retirement plan or an
individual-type retirement account are not subject to sales charges if American
Funds Service Company is notified of the repayment.

TRANSFERS TO COLLEGEAMERICA -- A transfer from the Virginia Prepaid
Education Program/SM/ or the Virginia Education Savings Trust/SM/ to a
CollegeAmerica account will be made with no sales charge. No commission
will be paid to the dealer on such a transfer.

DEALER COMMISSIONS AND COMPENSATION -- Commissions (up to 1.00%) are paid to
dealers who initiate and are responsible for certain Class A share purchases not
subject to sales charges. These purchases consist of purchases of $1 million or
more, purchases by employer-sponsored defined contribution-type retirement plans
investing $1 million or more or with 100 or more eligible employees, and
purchases made at net asset value by certain retirement plans, endowments and
foundations with assets of $50 million or more. Commissions on such investments
(other than IRA rollover assets that roll over at no sales charge under the
fund's IRA rollover policy as described in the prospectus) are paid to dealers
at the following rates: 1.00% on amounts to $4 million, 0.50% on amounts over $4
million to $10 million and 0.25% on amounts over $10 million. Commissions are
based on cumulative investments and are not annually reset.

A dealer concession of up to 1% may be paid by the fund under its Class A plan
of distribution to reimburse the Principal Underwriter in connection with dealer
and wholesaler compensation paid by it with respect to investments made with no
initial sales charge.

SALES CHARGE REDUCTIONS AND WAIVERS

REDUCING YOUR CLASS A SALES CHARGE -- As described in the prospectus, there are
various ways to reduce your sales charge when purchasing Class A shares.
Additional information about Class A sales charge reductions is provided below.

U.S. Government Securities Fund -- Page 39
<PAGE>

STATEMENT OF INTENTION -- By establishing a statement of intention (the
"Statement"), you enter into a nonbinding commitment to purchase shares of
American Funds non-money market funds over a 13-month period and receive
the same sales charge (expressed as a percentage of your purchases) as if
all shares had been purchased at once.

The market value of your existing holdings eligible to be aggregated (see
below) as of the day immediately before the start of the Statement period
may be credited toward satisfying the Statement.

The Statement may be revised upward at any time during the Statement
period, and such a revision will be treated as a new Statement, except that
the Statement period during which the purchases must be made will remain
unchanged. Purchases made from the date of revision will receive the
reduced sales charge, if any, resulting from the revised Statement.

The Statement will be considered completed if the shareholder dies within
the 13-month Statement period. Commissions to dealers will not be adjusted
or paid on the difference between the Statement amount and the amount
actually invested before the shareholder's death.

When a shareholder elects to use a Statement, shares equal to 5% of the
dollar amount specified in the Statement may be held in escrow in the
shareholder's account out of the initial purchase (or subsequent purchases,
if necessary) by the Transfer Agent. All dividends and any capital gain
distributions on shares held in escrow will be credited to the
shareholder's account in shares (or paid in cash, if requested). If the
intended investment is not completed within the specified Statement period,
the purchaser may be required to remit to the Principal Underwriter the
difference between the sales charge actually paid and the sales charge
which would have been paid if the total of such purchases had been made at
a single time. Any dealers assigned to the shareholder's account at the
time a purchase was made during the Statement period will receive a
corresponding commission adjustment if appropriate. If the difference is
not paid by the close of the Statement period, the appropriate number of
shares held in escrow will be redeemed to pay such difference. If the
proceeds from this redemption are inadequate, the purchaser may be liable
to the Principal Underwriter for the balance still outstanding.

Certain payroll deduction retirement plans purchasing Class A shares under
a Statement on or before November 12, 2006, may continue to purchase Class
A shares at the sales charge determined by that particular Statement until
the plans' values reach the amounts specified in their Statements. Upon
reaching such amounts, the Statements for these plans will be deemed
completed and will terminate at that time. After such termination, these
plans are eligible for additional sales charge reductions by meeting the
criteria under the fund's rights of accumulation policy.

If you make an American Funds purchase under a statement of intention
prior to April 1, 2007, purchases of American Legacy variable annuity
contracts and variable life insurance policies may also be credited toward
completion of that statement of intention.

Shareholders purchasing shares at a reduced sales charge under a Statement
indicate their acceptance of these terms and those in the prospectus with
their first purchase.

AGGREGATION -- Qualifying investments for aggregation include those made by
you and your "immediate family" as defined in the prospectus, if all
parties are purchasing shares for their own accounts and/or:

U.S. Government Securities Fund -- Page 40
<PAGE>

. individual-type employee benefit plans, such as an IRA, individual
403(b) plan (see exception in "Purchases by certain 403(b) plans"
under "Sales charges") or single-participant Keogh-type plan;

. business accounts solely controlled by you or your immediate family
(for example, you own the entire business);

. trust accounts established by you or your immediate family (for trusts
with only one primary beneficiary, upon the trustor's death the trust
account may be aggregated with such beneficiary's own accounts; for
trusts with multiple primary beneficiaries, upon the trustor's death
the trustees of the trust may instruct American Funds Service Company
to establish separate trust accounts for each primary beneficiary;
each primary beneficiary's separate trust account may then be
aggregated with such beneficiary's own accounts);

. endowments or foundations established and controlled by you or your
immediate family; 529 accounts, which will be aggregated at the
account owner level (Class 529-E accounts may only be aggregated with
an eligible employer plan).

Individual purchases by a trustee(s) or other fiduciary(ies) may also be
aggregated if the investments are:

. for a single trust estate or fiduciary account, including employee
benefit plans other than the individual-type employee benefit plans
described above;

. made for two or more employee benefit plans of a single employer or of
affiliated employers as defined in the 1940 Act, excluding the
individual-type employee benefit plans described above;

. for a diversified common trust fund or other diversified pooled
account not specifically formed for the purpose of accumulating fund
shares;

. for nonprofit, charitable or educational organizations, or any
endowments or foundations established and controlled by such
organizations, or any employer-sponsored retirement plans established
for the benefit of the employees of such organizations, their
endowments, or their foundations; or

. for individually established participant accounts of a 403(b) plan
that is treated similarly to an employer-sponsored plan for sales
charge purposes (see "Purchases by certain 403(b) plans" under "Sales
charges" above), or made for two or more such 403(b) plans that are
treated similarly to employer-sponsored plans for sales charge
purposes, in each case of a single employer or affiliated employers as
defined in the 1940 Act.

Purchases made for nominee or street name accounts (securities held in the
name of an investment dealer or another nominee such as a bank trust
department instead of the customer) may not be aggregated with those made
for other accounts and may not be aggregated with other nominee or street
name accounts unless otherwise qualified as described above.

CONCURRENT PURCHASES -- As described in the prospectus, you may reduce your
Class A sales charge by combining purchases of all classes of shares in the
American Funds, as well as individual holdings in Endowments. Shares of
money market funds purchased through an exchange, reinvestment or
cross-reinvestment from a fund having a sales charge also qualify. However,
direct purchases of American Funds money market funds are excluded.

U.S. Government Securities Fund -- Page 41
<PAGE>

RIGHTS OF ACCUMULATION -- Subject to the limitations described in the
aggregation policy, you may take into account your accumulated holdings in
all share classes of the American Funds, as well as your holdings in
Endowments, to determine your sales charge on investments in accounts
eligible to be aggregated. Subject to your investment dealer's or
recordkeeper's capabilities, your accumulated holdings will be calculated
as the higher of (a) the current value of your existing holdings (the
"market value") or (b) the amount you invested (including reinvested
dividends and capital gains, but excluding capital appreciation) less any
withdrawals (the "cost value"). Depending on the entity on whose books your
account is held, the value of your holdings in that account may not be
eligible for calculation at cost value. For example, accounts held in
nominee or street name are not eligible for calculation at cost value and
instead will be calculated at market value for purposes of rights of
accumulation.

The value of all of your holdings in accounts established in calendar year
2005 or earlier will be assigned an initial cost value equal to the market
value of those holdings as of the last business day of 2005. Thereafter,
the cost value of such accounts will increase or decrease according to
actual investments or withdrawals. You must contact your financial adviser
or American Funds Service Company if you have additional information that
is relevant to the calculation of the value of your holdings.

If you make a gift of American Funds Class A shares, upon your request, you
may purchase the shares at the sales charge discount allowed under rights
of accumulation of all of your American Funds accounts.

CDSC WAIVERS FOR CLASS A, B AND C SHARES -- As noted in the prospectus, a
contingent deferred sales charge ("CDSC") may be waived for redemptions due to
death or postpurchase disability of a shareholder (this generally excludes
accounts registered in the names of trusts and other entities). In the case of
joint tenant accounts, if one joint tenant dies, a surviving joint tenant, at
the time he or she notifies the Transfer Agent of the other joint tenant's death
and removes the decedent's name from the account, may redeem shares from the
account without incurring a CDSC. Redemptions made after the Transfer Agent is
notified of the death of a joint tenant will be subject to a CDSC.

In addition, a CDSC may be waived for the following types of transactions, if
together they do not exceed 12% of the value of an "account" (defined below)
annually (the "12% limit"):

. Required minimum distributions taken from retirement accounts upon the
shareholder's attainment of age 70-1/2 (required minimum distributions
that continue to be taken by the beneficiary(ies) after the account
owner is deceased also qualify for a waiver).

U.S. Government Securities Fund -- Page 42
<PAGE>

. Redemptions through a systematic withdrawal plan (SWP) (see "Automatic
withdrawals" under "Shareholder account services and privileges"
below). For each SWP payment, assets that are not subject to a CDSC,
such as appreciation on shares and shares acquired through
reinvestment of dividends and/or capital gain distributions, will be
redeemed first and will count toward the 12% limit. If there is an
insufficient amount of assets not subject to a CDSC to cover a
particular SWP payment, shares subject to the lowest CDSC will be
redeemed next until the 12% limit is reached. Any dividends and/or
capital gain distributions taken in cash by a shareholder who receives
payments through a SWP will also count toward the 12% limit. In the
case of a SWP, the 12% limit is calculated at the time a systematic
redemption is first made, and is recalculated at the time each
additional systematic redemption is made. Shareholders who establish a
SWP should be aware that the amount of a payment not subject to a CDSC
may vary over time depending on fluctuations in the value of their
accounts. This privilege may be revised or terminated at any time.

For purposes of this paragraph, "account" means:

. in the case of Class A shares, your investment in Class A shares of
all American Funds (investments representing direct purchases of
American Funds money market funds are excluded);

. in the case of Class B shares, your investment in Class B shares of
the particular fund from which you are making the redemption; and

. in the case of Class C shares, your investment in Class C shares of
the particular fund from which you are making the redemption.

CDSC waivers are allowed only in the cases listed here and in the prospectus.
For example, CDSC waivers will not be allowed on redemptions of Class 529-B and
529-C shares due to termination of CollegeAmerica; a determination by the
Internal Revenue Service that CollegeAmerica does not qualify as a qualified
tuition program under the Code; proposal or enactment of law that eliminates or
limits the tax-favored status of CollegeAmerica; or elimination of the fund by
the Virginia College Savings Plan as an option for additional investment within
CollegeAmerica.

SELLING SHARES

The methods for selling (redeeming) shares are described more fully in the
prospectus. If you wish to sell your shares by contacting American Funds Service
Company directly, any such request must be signed by the registered
shareholders. To contact American Funds Service Company via overnight mail or
courier service, see "Purchase and exchange of shares."

A signature guarantee may be required for certain redemptions. In such an event,
your signature may be guaranteed by a domestic stock exchange or the National
Association of Securities Dealers, Inc., bank, savings association or credit
union that is an eligible guarantor institution. The Transfer Agent reserves the
right to require a signature guarantee on any redemptions.

Additional documentation may be required for sales of shares held in corporate,
partnership or fiduciary accounts. You must include with your written request
any shares you wish to sell that are in certificate form.

U.S. Government Securities Fund -- Page 43
<PAGE>

If you sell Class A, B or C shares and request a specific dollar amount to be
sold, we will sell sufficient shares so that the sale proceeds, after deducting
any applicable CDSC, equals the dollar amount requested.

Redemption proceeds will not be mailed until sufficient time has passed to
provide reasonable assurance that checks or drafts (including certified or
cashier's checks) for shares purchased have cleared (which may take up to 10
business days from the purchase date). Except for delays relating to clearance
of checks for share purchases or in extraordinary circumstances (and as
permissible under the 1940 Act), sale proceeds will be paid on or before the
seventh day following receipt and acceptance of an order. Interest will not
accrue or be paid on amounts that represent uncashed distribution or redemption
checks.

You may request that redemption proceeds of $1,000 or more from money market
funds be wired to your bank by writing American Funds Service Company. A
signature guarantee is required on all requests to wire funds.

SHAREHOLDER ACCOUNT SERVICES AND PRIVILEGES

The following services and privileges are generally available to all
shareholders. However, certain services and privileges may not be available for
Class 529 shareholders or if your account is held with an investment dealer or
through an employer-sponsored retirement plan.

AUTOMATIC INVESTMENT PLAN -- An automatic investment plan enables you to make
monthly or quarterly investments in the American Funds through automatic debits
from your bank account. To set up a plan, you must fill out an account
application and specify the amount that you would like to invest ($50 minimum
per fund; $25 minimum per fund in the case of employer-sponsored 529 accounts)
and the date on which you would like your investments to occur. The plan will
begin within 30 days after your account application is received. Your bank
account will be debited on the day or a few days before your investment is made,
depending on the bank's capabilities. The Transfer Agent will then invest your
money into the fund you specified on or around the date you specified. If the
date you specified falls on a weekend or holiday, your money will be invested on
the following business day. However, if the following business day falls in the
next month, your money will be invested on the business day immediately
preceding the weekend or holiday. If your bank account cannot be debited due to
insufficient funds, a stop-payment or the closing of the account, the plan may
be terminated and the related investment reversed. You may change the amount of
the investment or discontinue the plan at any time by contacting the Transfer
Agent.

AUTOMATIC REINVESTMENT -- Dividends and capital gain distributions are
reinvested in additional shares of the same class and fund at net asset value
unless you indicate otherwise on the account application. You also may elect to
have dividends and/or capital gain distributions paid in cash by informing the
fund, the Transfer Agent or your investment dealer. Dividends and capital gain
distributions paid to retirement plan shareholders or shareholders of the 529
share classes will be automatically reinvested.

If you have elected to receive dividends and/or capital gain distributions in
cash, and the postal or other delivery service is unable to deliver checks to
your address of record, or you do not respond to mailings from American Funds
Service Company with regard to uncashed distribution checks, your distribution
option will automatically be converted to having all dividends and other
distributions reinvested in additional shares.

U.S. Government Securities Fund -- Page 44
<PAGE>

CROSS-REINVESTMENT OF DIVIDENDS AND DISTRIBUTIONS -- For all share classes,
except the 529 classes of shares, you may cross-reinvest dividends and capital
gains (distributions) into other American Funds in the same share class at net
asset value, subject to the following conditions:

(1) the aggregate value of your account(s) in the fund(s) paying distributions
equals or exceeds $5,000 (this is waived if the value of the account in the fund
receiving the distributions equals or exceeds that fund's minimum initial
investment requirement);

(2) if the value of the account of the fund receiving distributions is below
the minimum initial investment requirement, distributions must be automatically
reinvested; and

(3) if you discontinue the cross-reinvestment of distributions, the value of
the account of the fund receiving distributions must equal or exceed the minimum
initial investment requirement. If you do not meet this requirement within 90
days of notification, the fund has the right to automatically redeem the
account.

AUTOMATIC EXCHANGES -- For all share classes, you may automatically exchange
shares of the same class in amounts of $50 or more among any of the American
Funds on any day (or preceding business day if the day falls on a nonbusiness
day) of each month you designate.

AUTOMATIC WITHDRAWALS -- For all share classes, except the R and 529 classes of
shares, you may automatically withdraw shares from any of the American Funds.
You can make automatic withdrawals of $50 or more as often as you wish if your
account is worth at least $10,000, or up to four times a year for an account
worth at least $5,000. You can designate the day of each period for withdrawals
and request that checks be sent to you or someone else. Withdrawals may also be
electronically deposited to your bank account. The Transfer Agent will withdraw
your money from the fund you specify on or around the date you specify. If the
date you specified falls on a weekend or holiday, the redemption will take place
on the previous business day. However, if the previous business day falls in the
preceding month, the redemption will take place on the following business day
after the weekend or holiday.

Withdrawal payments are not to be considered as dividends, yield or income.
Automatic investments may not be made into a shareholder account from which
there are automatic withdrawals. Withdrawals of amounts exceeding reinvested
dividends and distributions and increases in share value would reduce the
aggregate value of the shareholder's account. The Transfer Agent arranges for
the redemption by the fund of sufficient shares, deposited by the shareholder
with the Transfer Agent, to provide the withdrawal payment specified.

ACCOUNT STATEMENTS -- Your account is opened in accordance with your
registration instructions. Transactions in the account, such as additional
investments, will be reflected on regular confirmation statements from the
Transfer Agent. Dividend and capital gain reinvestments, purchases through
automatic investment plans and certain retirement plans, as well as automatic
exchanges and withdrawals will be confirmed at least quarterly.

AMERICAN FUNDSLINE AND AMERICANFUNDS.COM -- You may check your share balance,
the price of your shares or your most recent account transaction; redeem shares
(up to $75,000 per American Funds shareholder each day) from nonretirement plan
accounts; or exchange shares around the clock with American FundsLine or using
americanfunds.com. To use American FundsLine, call 800/325-3590 from a
TouchTone(TM) telephone. Redemptions and exchanges through American FundsLine
and americanfunds.com are subject to the conditions noted above

U.S. Government Securities Fund -- Page 45
<PAGE>

and in "Telephone and Internet purchases, redemptions and exchanges" below. You
will need your fund number (see the list of the American Funds under "General
information -- fund numbers"), personal identification number (generally the
last four digits of your Social Security number or other tax identification
number associated with your account) and account number.

Generally, all shareholders are automatically eligible to use these services.
However, if you are not currently authorized to do so, you may complete an
American FundsLink Authorization Form. Once you establish this privilege, you,
your financial adviser or any person with your account information may use these
services.

TELEPHONE AND INTERNET PURCHASES, REDEMPTIONS AND EXCHANGES -- By using the
telephone (including American FundsLine) or the Internet (including
americanfunds.com), or fax purchase, redemption and/or exchange options, you
agree to hold the fund, the Transfer Agent, any of its affiliates or mutual
funds managed by such affiliates, and each of their respective directors,
trustees, officers, employees and agents harmless from any losses, expenses,
costs or liability (including attorney fees) that may be incurred in connection
with the exercise of these privileges. Generally, all shareholders are
automatically eligible to use these services. However, you may elect to opt out
of these services by writing the Transfer Agent (you may also reinstate them at
any time by writing the Transfer Agent). If the Transfer Agent does not employ
reasonable procedures to confirm that the instructions received from any person
with appropriate account information are genuine, it and/or the fund may be
liable for losses due to unauthorized or fraudulent instructions. In the event
that shareholders are unable to reach the fund by telephone because of technical
difficulties, market conditions or a natural disaster, redemption and exchange
requests may be made in writing only.

CHECKWRITING -- You may establish check writing privileges for Class A shares
(but not Class 529-A shares) of American Funds money market funds. This can be
done by using an account application. If you request check writing privileges,
you will be provided with checks that you may use to draw against your account.
These checks may be made payable to anyone you designate and must be signed by
the authorized number of registered shareholders exactly as indicated on your
account application.

REDEMPTION OF SHARES -- The fund's Declaration of Trust permits the fund to
direct the Transfer Agent to redeem the shares of any shareholder for their then
current net asset value per share if at such time the shareholder of record owns
shares having an aggregate net asset value of less than the minimum initial
investment amount required of new shareholders as set forth in the fund's
current registration statement under the 1940 Act, and subject to such further
terms and conditions as the board of trustees of the fund may from time to time
adopt.

SHARE CERTIFICATES -- Shares are credited to your account and certificates are
not issued unless you request them by contacting the Transfer Agent.
Certificates are not available for the 529 or R share classes.

GENERAL INFORMATION

CUSTODIAN OF ASSETS -- Securities and cash owned by the fund, including proceeds
from the sale of shares of the fund and of securities in the fund's portfolio,
are held by JPMorgan Chase Bank, 270 Park Avenue, New York, NY 10017-2070, as
Custodian. If the fund holds non-U.S. securities, the Custodian may hold these
securities pursuant to subcustodial arrangements in non-U.S. banks or non-U.S.
branches of U.S. banks.

U.S. Government Securities Fund -- Page 46
<PAGE>

TRANSFER AGENT -- American Funds Service Company, a wholly owned subsidiary of
the investment adviser, maintains the records of shareholder accounts, processes
purchases and redemptions of the fund's shares, acts as dividend and capital
gain distribution disbursing agent, and performs other related shareholder
service functions. The principal office of American Funds Service Company is
located at 135 South State College Boulevard, Brea, CA 92821-5823. American
Funds Service Company was paid a fee of $2,754,000 for Class A shares and
$260,000 for Class B shares for the 2006 fiscal year. American Funds Service
Company is also compensated for certain transfer agency services provided to all
other share classes from the administrative services fees paid to Capital
Research and Management Company, as described under "Administrative services
agreement."

In the case of certain shareholder accounts, third parties who may be
unaffiliated with the investment adviser provide transfer agency and shareholder
services in place of American Funds Service Company. These services are rendered
under agreements with American Funds Service Company or its affiliates and the
third parties receive compensation according to such agreements. Compensation
for transfer agency and shareholder services, whether paid to American Funds
Service Company or such third parties, is ultimately paid from fund assets and
is reflected in the expenses of the fund as disclosed in the prospectus.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM -- Deloitte & Touche LLP, 695 Town
Center Drive, Costa Mesa, California 92626, serves as the fund's independent
registered public accounting firm, providing audit services, preparation of tax
returns and review of certain documents to be filed with the Securities and
Exchange Commission. The financial statements included in this statement of
additional information from the annual report have been so included in reliance
on the report of Deloitte & Touche LLP, independent registered public accounting
firm, given on the authority of said firm as experts in accounting and auditing.
The selection of the fund's independent registered public accounting firm is
reviewed and determined annually by the board of trustees.

INDEPENDENT LEGAL COUNSEL -- Paul, Hastings, Janofsky & Walker LLP, 515 South
Flower Street, Los Angeles, CA 90071, serves as counsel for the fund and for
independent trustees in their capacities as such. Certain legal matters in
connection with certain shares of beneficial interest offered by the prospectus
have been passed upon for the fund by Paul, Hastings, Janofsky & Walker LLP.
Counsel does not provide legal services to the fund's investment adviser or any
of its affiliated companies. A determination with respect to the independence of
the fund's "independent legal counsel" will be made at least annually by the
independent trustees of the fund, as prescribed by the 1940 Act and related
rules.

PROSPECTUSES, REPORTS TO SHAREHOLDERS AND PROXY STATEMENTS -- The fund's fiscal
year ends on August 31. Shareholders are provided updated prospectuses annually
and at least semiannually with reports showing the fund's investment portfolio
or summary investment portfolio, financial statements and other information. The
fund's annual financial statements are audited by the fund's independent
registered public accounting firm, Deloitte & Touche LLP. In addition,
shareholders may also receive proxy statements for the fund. In an effort to
reduce the volume of mail shareholders receive from the fund when a household
owns more than one account, the Transfer Agent has taken steps to eliminate
duplicate mailings of prospectuses, shareholder reports and proxy statements. To
receive additional copies of a prospectus, report or proxy statement,
shareholders should contact the Transfer Agent.

U.S. Government Securities Fund -- Page 47
<PAGE>

SHAREHOLDER AND TRUSTEE RESPONSIBILITY -- Under the laws of certain states,
including Massachusetts, where the fund was organized, and California, where the
fund's principal office is located, shareholders of a Massachusetts business
trust may, under certain circumstances, be held personally liable as partners
for the obligations of the fund. However, the risk of a shareholder incurring
any financial loss on account of shareholder liability is limited to
circumstances in which a fund itself would be unable to meet its obligations.
The Declaration of Trust contains an express disclaimer of shareholder liability
for acts, omissions, obligations or affairs of the fund and provides that notice
of the disclaimer may be given in each agreement, obligation, or instrument
which is entered into or executed by the fund or trustees. The Declaration of
Trust provides for indemnification out of fund property of any shareholder held
personally liable for the obligations of the fund and also provides for the fund
to reimburse such shareholder for all legal and other expenses reasonably
incurred in connection with any such claim or liability.

Under the Declaration of Trust, the trustees, officers, employees or agents of
the fund are not liable for actions or failure to act; however, they are not
protected from liability by reason of their willful misfeasance, bad faith,
gross negligence, or reckless disregard of the duties involved in the conduct of
their office.

CODES OF ETHICS -- The fund and Capital Research and Management Company and its
affiliated companies, including the fund's Principal Underwriter, have adopted
codes of ethics that allow for personal investments, including securities in
which the fund may invest from time to time. These codes include a ban on
acquisitions of securities pursuant to an initial public offering; restrictions
on acquisitions of private placement securities; preclearance and reporting
requirements; review of duplicate confirmation statements; annual
recertification of compliance with codes of ethics; blackout periods on personal
investing for certain investment personnel; ban on short-term trading profits
for investment personnel; limitations on service as a director of publicly
traded companies; and disclosure of personal securities transactions.

LEGAL PROCEEDINGS -- On February 16, 2005, the NASD filed an administrative
complaint against the Principal Underwriter. The complaint alleges violations of
certain NASD rules by the Principal Underwriter with respect to the selection of
broker-dealer firms that buy and sell securities for mutual fund investment
portfolios. The complaint seeks sanctions, restitution and disgorgement. On
August 30, 2006, the NASD Hearing Panel ruled against the Principal Underwriter
and imposed a $5 million fine. The Principal Underwriter has appealed this
decision to the NASD's National Adjudicatory Council.

On March 24, 2005, the investment adviser and Principal Underwriter filed a
complaint against the Attorney General of the State of California in Los Angeles
County Superior Court. The complaint alleged that the Attorney General
threatened to take enforcement actions against the investment adviser and
Principal Underwriter that are without merit and preempted by federal law. On
the same day, following the filing of the investment adviser's and Principal
Underwriter's complaint, the Attorney General of the State of California filed a
complaint against the Principal Underwriter and investment adviser. Filed in Los
Angeles County Superior Court, the Attorney General's complaint alleged
violations of certain sections of the California Corporations Code with respect
to so-called "revenue sharing" disclosures in mutual fund prospectuses and
statements of additional information. On November 22, 2005, the Los Angeles
Superior Court dismissed the Attorney General's complaint. The Attorney General
subsequently appealed the Superior Court's decision to California's Court of
Appeal for the Second Appellate District. On January 26, 2007, the Court of
Appeal issued a ruling allowing the California Attorney General to proceed with
his civil action.

U.S. Government Securities Fund -- Page 48
<PAGE>

The investment adviser and Principal Underwriter believe that the likelihood
that these matters could have a material adverse effect on the fund or on the
ability of the investment adviser or Principal Underwriter to perform their
contracts with the fund is remote. The SEC is conducting a related investigation
as of the date of this statement of additional information. The investment
adviser and Principal Underwriter are cooperating fully. In addition, class
action lawsuits have been filed in the U.S. District Court, Central District of
California, relating to these matters. The investment adviser believes that
these suits are without merit and will defend itself vigorously. Further updates
on these issues will be available on the American Funds website
(americanfunds.com) under "American Funds regulatory matters."

OTHER INFORMATION -- The financial statements including the investment portfolio

APPENDIX

The following descriptions of debt security ratings are based on information
provided by Moody's Investors Service and Standard & Poor's Corporation.

DESCRIPTION OF BOND RATINGS

MOODY'S
LONG-TERM RATING DEFINITIONS

Aaa
Obligations rated Aaa are judged to be of the highest quality, with minimal
credit risk.

Aa
Obligations rated Aa are judged to be of high quality and are subject to very
low credit risk.

A
Obligations rated A are considered upper-medium grade and are subject to low
credit risk.

Baa
Obligations rated Baa are subject to moderate credit risk. They are considered
medium-grade and as such may possess certain speculative characteristics.

Ba
Obligations rated Ba are judged to have speculative elements and are subject to
substantial credit risk.

B
Obligations rated B are considered speculative and are subject to high credit
risk.

Caa
Obligations rated Caa are judged to be of poor standing and are subject to very
high credit risk.

Ca
Obligations rated Ca are highly speculative and are likely in, or very near,
default, with some prospect of recovery of principal and interest.

C
Obligations rated C are the lowest rated class of bonds and are typically in
default, with little prospect for recovery of principal or interest.

NOTE: Moody's appends numerical modifiers 1, 2, and 3 to each generic rating
classification from Aa through Caa. The modifier 1 indicates that the obligation
ranks in the higher end of its generic rating category; the modifier 2 indicates
a mid-range ranking; and the modifier 3 indicates a ranking in the lower end of
that generic rating category.

STANDARD & POOR'S
LONG-TERM ISSUE CREDIT RATINGS

AAA
An obligation rated AAA has the highest rating assigned by Standard & Poor's.
The obligor's capacity to meet its financial commitment on the obligation is
extremely strong.

AA
An obligation rated AA differs from the highest-rated obligations only in small
degree. The obligor's capacity to meet its financial commitment on the
obligation is very strong.

A
An obligation rated A is somewhat more susceptible to the adverse effects of
changes in circumstances and economic conditions than obligations in
higher-rated categories. However, the obligor's capacity to meet its financial
commitment on the obligation is still strong.

BBB
An obligation rated BBB exhibits adequate protection parameters. However,
adverse economic conditions or changing circumstances are more likely to lead to
a weakened capacity of the obligor to meet its financial commitment on the
obligation.

BB, B, CCC, CC, AND C
Obligations rated BB, B, CCC, CC, and C are regarded as having significant
speculative characteristics. BB indicates the least degree of speculation and C
the highest. While such obligations will likely have some quality and protective
characteristics, these may be outweighed by large uncertainties or major
exposures to adverse conditions.

BB
An obligation rated BB is less vulnerable to nonpayment than other speculative
issues. However, it faces major ongoing uncertainties or exposure to adverse
business, financial, or economic conditions which could lead to the obligor's
inadequate capacity to meet its financial commitment on the obligation.

B
An obligation rated B is more vulnerable to nonpayment than obligations rated
BB, but the obligor currently has the capacity to meet its financial commitment
on the obligation. Adverse business, financial, or economic conditions will
likely impair the obligor's capacity or willingness to meet its financial
commitment on the obligation.

CCC
An obligation rated CCC is currently vulnerable to nonpayment and is dependent
upon favorable business, financial, and economic conditions for the obligor to
meet its financial commitment on the obligation. In the event of adverse
business, financial, or economic conditions, the obligor is not likely to have
the capacity to meet its financial commitment on the obligation.

CC
An obligation rated CC is currently highly vulnerable to nonpayment.

U.S. Government Securities Fund -- Page 54
<PAGE>

C
The C rating may be used to cover a situation where a bankruptcy petition has
been filed or similar action has been taken, but payments on this obligation are
being continued.

D
An obligation rated D is in payment default. The D rating category is used when
payments on an obligation are not made on the date due even if the applicable
grace period has not expired, unless Standard & Poor's believes that such
payments will be made during such grace period. The D rating also will be used
upon the filing of a bankruptcy petition or the taking of a similar action if
payments on an obligation are jeopardized.

PLUS (+) OR MINUS (-)
The ratings from AA to CCC may be modified by the addition of a plus or minus
sign to show relative standing within the major rating categories.

FITCH

LONG-TERM CREDIT RATINGS

AAA
Highest credit quality. 'AAA' ratings denote the lowest expectation of credit
risk. They are assigned only in case of exceptionally strong capacity for
payment of financial commitments. This capacity is highly unlikely to be
adversely affected by foreseeable events.

AA
Very high credit quality. 'AA' ratings denote expectations of very low credit
risk. They indicate very strong capacity for payment of financial commitments.
This capacity is not significantly vulnerable to foreseeable events.

High credit quality. 'A' ratings denote expectations of low credit risk. The
capacity for payment of financial commitments is considered strong. This
capacity may, nevertheless, be more vulnerable to changes in circumstances or in
economic conditions than is the case for higher ratings.

BBB
Good credit quality. 'BBB' ratings indicate that there is currently expectations
of low credit risk. The capacity for payment of financial commitments is
considered adequate but adverse changes in circumstances and economic conditions
are more likely to impair this capacity. This is the lowest investment grade
category.

BB
Speculative. 'BB' ratings indicate that there is a possibility of credit risk
developing, particularly as the result of adverse economic change over time;
however, business or financial alternatives may be available to allow financial
commitments to be met. Securities rated in this category are not investment
grade.

U.S. Government Securities Fund -- Page 55
<PAGE>

Highly speculative.
. For issuers and performing obligations, 'B' ratings indicate that
significant credit risk is present, but a limited margin of safety remains.
Financial commitments are currently being met; however, capacity for
continued payment is contingent upon a sustained, favorable business and
economic environment.
. For individual obligations, may indicate distressed or defaulted
obligations with potential for extremely high recoveries. Such obligations
would possess a Recovery Rating of 'R1' (outstanding).

CCC
. For issuers and performing obligations, default is a real possibility.
Capacity for meeting financial commitments is solely reliant upon
sustained, favorable business or economic conditions.
. For individual obligations, may indicate distressed or defaulted
obligations with potential for average to superior levels of recovery.
Differences in credit quality may be denoted by plus/minus distinctions.
Such obligations typically would possess a Recovery Rating of 'R2'
(superior), or 'R3' (good) or 'R4' (average).

CC
. For issuers and performing obligations, default of some kind appears
probable.
. For individual obligations, may indicate distressed or defaulted
obligations with a Recovery Rating of 'R4' (average) or 'R5' (below
average).

C
. For issuers and performing obligations, default is imminent.
. For individual obligations, may indicate distressed or defaulted
obligations with potential for below-average to poor recoveries. Such
obligations would possess a Recovery Rating of 'R6' (poor).

RD
Indicates an entity that has failed to make due payments (within the applicable
grace period) on some but not all material financial obligations, but continues
to honor other classes of obligations.

D
Indicates an entity or sovereign that has defaulted on all of its financial
obligations. Default generally is defined as the following:
The modifiers "+" or "-" may be appended to a rating to denote relative
status within major rating categories. Such suffixes are not added to the
'AAA' Long-term rating category, to categories below 'CCC', or to
Short-term ratings other than 'F1'. (The +/- modifiers are only used to
denote issues within the CCC category, whereas issuers are only rated CCC
without the use of modifiers.

DESCRIPTION OF COMMERCIAL PAPER RATINGS

MOODY'S
COMMERCIAL PAPER RATINGS (HIGHEST THREE RATINGS)

P-1
Issuers (or supporting institutions) rated Prime-1 have a superior ability to
repay short-term debt obligations.

P-2
Issuers (or supporting institutions) rated Prime-2 have a strong ability to
repay short-term debt obligations.

P-3
Issuers (or supporting institutions) rated Prime-3 have an acceptable ability to
repay short-term obligations.

STANDARD & POOR'S
COMMERCIAL PAPER RATINGS (HIGHEST THREE RATINGS)

A-1
A short-term obligation rated A-1 is rated in the highest category by Standard &
Poor's. The obligor's capacity to meet its financial commitment on the
obligation is strong. Within this category, certain obligations are designated
with a plus sign (+). This indicates that the obligor's capacity to meet its
financial commitment on these obligations is extremely strong.

A-2
A short-term obligation rated A-2 is somewhat more susceptible to the adverse
effects of changes in circumstances and economic conditions than obligations in
higher rating categories. However, the obligor's capacity to meet its financial
commitment on the obligation is satisfactory.

A-3
A short-term obligation rated A-3 exhibits adequate protection parameters.
However, adverse economic conditions or changing circumstances are more likely
to lead to a weakened capacity of the obligor to meet its financial commitment
on the obligation.

Notes to financial statements

1.	Organization and significant accounting policies

Organization - The American Funds Income Series (the "trust") is registered under the Investment Company Act of 1940 as an open-end, diversified management investment company and has initially issued one series of shares, U.S. Government Securities Fund (the "fund"). The fund seeks a high level of current income, consistent with prudent investment risk and preservation of capital, by investing primarily in obligations guaranteed or sponsored by the United States government. The fund may also invest in nongovernment issues rated Aaa/AAA or equivalent.

The fund offers 14 share classes consisting of four retail share classes, five CollegeAmerica® savings plan share classes and five retirement plan share classes. The CollegeAmerica savings plan share classes (529-A, 529-B, 529-C, 529-E and 529-F) can be utilized to save for college education. The five retirement plan share classes (R-1, R-2, R-3, R-4 and R-5) are sold without any sales charges and do not carry any conversion rights. The fund’s share classes are described below:

Share class	Initial sales charge	Contingent deferred sales charge upon redemption	Conversion feature
Class A and 529-A	Up to 3.75%	None (except 1% for certain redemptions within one year of purchase without an initial sales charge)	None
Class B and 529-B	None	Declines from 5% to 0% for redemptions within six years of purchase	Class B and 529-B convert to Class A and 529-A, respectively, after eight years
Class C	None	1% for redemptions within one year of purchase	Class C converts to Class F after 10 years
Class 529-C	None	1% for redemptions within one year of purchase	None
Class 529-E	None	None	None
Class F and 529-F	None	None	None
Class R-1, R-2, R-3, R-4 and R-5	None	None	None

Holders of all share classes have equal pro rata rights to assets, dividends and liquidation proceeds. Each share class has identical voting rights, except for the exclusive right to vote on matters affecting only its class. Share classes have different fees and expenses ("class-specific fees and expenses"), primarily due to different arrangements for distribution, administrative and shareholder services. Differences in class-specific fees and expenses will result in differences in net investment income and, therefore, the payment of different per-share dividends by each class.

Significant accounting policies - The financial statements have been prepared to comply with accounting principles generally accepted in the United States of America. These principles require management to make estimates and assumptions that affect reported amounts and disclosures. Actual results could differ from those estimates. The following is a summary of the significant accounting policies followed by the fund:

Security valuation - Fixed-income securities, including short-term securities purchased with more than 60 days left to maturity, are valued at prices obtained from an independent pricing service when such prices are available. However, where the investment adviser deems it appropriate, such securities will be valued at the mean quoted bid and asked prices (or bid prices, if asked prices are not available) or at prices for securities of comparable maturity, quality and type. Short-term securities purchased within 60 days to maturity are valued at amortized cost, which approximates market value. The value of short-term securities originally purchased with maturities greater than 60 days is determined based on an amortized value to par when they reach 60 days or less remaining to maturity. The ability of the issuers of the debt securities held by the fund to meet their obligations may be affected by economic developments in a specific industry, state or region. Securities and other assets for which representative market quotations are not readily available or are considered unreliable are fair valued as determined in good faith under procedures adopted by authority of the fund's board of trustees. Various factors may be reviewed in order to make a good faith determination of a security’s fair value. These factors include, but are not limited to, the type and cost of the security; contractual or legal restrictions on resale of the security; relevant financial or business developments of the issuer; actively traded similar or related securities; conversion or exchange rights on the security; related corporate actions; significant events occurring after the close of trading in the security; and changes in overall market conditions.

Security transactions and related investment income - Security transactions are recorded by the fund as of the date the trades are executed with brokers. Realized gains and losses from security transactions are determined based on the specific identified cost of the securities. In the event a security is purchased with a delayed payment date, the fund will segregate liquid assets sufficient to meet its payment obligations. Interest income is recognized on an accrual basis. Market discounts, premiums and original issue discounts on fixed-income securities are amortized daily over the expected life of the security.

Class allocations - Income, fees and expenses (other than class-specific fees and expenses) are allocated daily among the various share classes based on the relative value of their settled shares. Realized and unrealized gains and losses are allocated daily among the various share classes based on their relative net assets. Class-specific fees and expenses, such as distribution, administrative and shareholder services, are charged directly to the respective share class.

Dividends and distributions to shareholders - Dividends paid to shareholders are declared daily after the determination of the fund’s net investment income and are paid to shareholders monthly. Distributions paid to shareholders are recorded on the ex-dividend date.

Mortgage dollar rolls - The fund may enter into mortgage dollar roll transactions in which the fund sells a mortgage-backed security to a counterparty and simultaneously enters into an agreement with the same counterparty to buy back a similar security on a specific future date at a predetermined price. Each mortgage dollar roll is treated as a financing transaction; therefore, any gain or loss is considered unrealized until the roll reaches completion. Risks may arise due to the delayed payment date and the potential inability of counterparties to complete the transaction. Income is generated as consideration for entering into these transactions and is included in interest income on the accompanying financial statements.

2. Federal income taxation and distributions

The fund complies with the requirements under Subchapter M of the Internal Revenue Code applicable to mutual funds and intends to distribute substantially all of its net taxable income and net capital gains each year. The fund is not subject to income taxes to the extent such distributions are made. Therefore, no federal income tax provision is required.

Distributions - Distributions paid to shareholders are based on net investment income and net realized gains determined on a tax basis, which may differ from net investment income and net realized gains for financial reporting purposes. These differences are due primarily to differing treatment for items such as capital losses related to sales of certain securities within 30 days of purchase; paydowns on fixed-income securities; and net capital losses. The fiscal year in which amounts are distributed may differ from the year in which the net investment income and net realized gains are recorded by the fund for financial reporting purposes.

During the year ended August 31, 2006, the fund reclassified $2,280,000 from accumulated net realized loss to undistributed net investment income, $4,377,000 from capital paid in on shares of beneficial interest to accumulated net realized loss and $3,000 from undistributed net investment income to capital paid in on shares of beneficial interest to align financial reporting with tax reporting.

As of August 31, 2006, the components of distributable earnings, unrealized appreciation (depreciation) and cost of investments on a tax basis were as follows:

	(dollars in thousands)
Undistributed ordinary income				$572
Capital loss carryforwards*:
Expiring 2008	$	( 5,664	)
Expiring 2009		( 8,375	)
Expiring 2014		(472	)		(14,511	)
Post-October capital loss deferrals (realized during the period November 1, 2005, through August 31, 2006)†					(28,054	)
Gross unrealized appreciation on investment securities					8,589
Gross unrealized depreciation on investment securities					(27,975	)
Net unrealized depreciation on investment securities					(19,386	)
Cost of investment securities					2,480,573

*Reflects the expiration of capital loss carryforwards of $4,377,000. The capital loss carryforwards will be used to offset any capital gains realized by the fund in future years through the expiration dates. The fund will not make distributions from capital gains while capital loss carryforwards remain.
†These deferrals are considered incurred in the subsequent year.

Ordinary income distributions paid or accrued to shareholders from net investment income were as follows (dollars in thousands):

3. Fees and transactions with related parties

Capital Research and Management Company ("CRMC"), the fund’s investment adviser, is the parent company of American Funds Service Company^SM ("AFS"), the fund’s transfer agent, and American Funds Distributors, Inc.^SM ("AFD"), the principal underwriter of the fund’s shares.

Investment advisory services - The Investment Advisory and Service Agreement with CRMC provides for monthly fees accrued daily. These fees are based on a declining series of annual rates beginning with 0.30% on the first $60 million of daily net assets and decreasing to 0.15% on such assets in excess of $3 billion. The agreement also provides for monthly fees, accrued daily, based on a declining series of rates beginning with 3.00% on the first $3,333,333 of the fund's monthly gross income and decreasing to 2.00% on such income in excess of $8,333,333. CRMC is currently waiving 10% of investment advisory services fees. During the year ended August 31, 2006, total investment advisory services fees waived by CRMC were $735,000. As a result, the fee shown on the accompanying financial statements of $7,351,000, which was equivalent to an annualized rate of 0.311%, was reduced to $6,616,000, or 0.280% of average daily net assets.

Class-specific fees and expenses - Expenses that are specific to individual share classes are accrued directly to the respective share class. The principal class-specific fees and expenses are described below:

Distribution services - The fund has adopted plans of distribution for all share classes, except Class R-5. Under the plans, the board of trustees approves certain categories of expenses that are used to finance activities primarily intended to sell fund shares and service existing accounts. The plans provide for payments, based on an annualized percentage of average daily net assets, ranging from 0.30% to 1.00% as noted on the following page. In some cases, the board of trustees has limited the amounts that may be paid to less than the maximum allowed by the plans. All share classes may use up to 0.25% of average daily net assets to pay service fees, or to compensate AFD for paying service fees, to firms that have entered into agreements with AFD to provide certain shareholder services. The remaining amounts available to be paid under each plan are paid to dealers to compensate them for their sales activities.

For Class A and 529-A, the board of trustees has also approved the reimbursement of dealer and wholesaler commissions paid by AFD for certain shares sold without a sales charge. These classes reimburse AFD for amounts billed within the prior 15 months but only to the extent that the overall annual expense limit of 0.30% is not exceeded. As of August 31, 2006, there were no unreimbursed expenses subject to reimbursement for Class A or 529-A.

Share class	Currently approved limits	Plan limits
Class A	0.30%	0.30%
Class 529-A	0.30	0.50
Class B and 529-B	1.00	1.00
Class C, 529-C and R-1	1.00	1.00
Class R-2	0.75	1.00
Class 529-E and R-3	0.50	0.75
Class F, 529-F and R-4	0.25	0.50

Transfer agent services - The fund has a transfer agent agreement with AFS for Class A and B. Under this agreement, these share classes compensate AFS for transfer agent services including shareholder recordkeeping, communications and transaction processing. AFS is also compensated for certain transfer agent services provided to all other share classes from the administrative services fees paid to CRMC described below.

Administrative services - The fund has an administrative services agreement with CRMC to provide transfer agent and other related shareholder services for all share classes other than Class A and B. Each relevant share class pays CRMC annual fees up to 0.15% (0.10% for Class R-5) based on its respective average daily net assets. Each relevant share class also pays AFS additional amounts for certain transfer agent services. CRMC and AFS may use these fees to compensate third parties for performing these services. CRMC has agreed to pay AFS on the fund's behalf for a portion of the transfer agent services fees for some of the retirement plan share classes. For the year ended August 31, 2006, the total administrative services fees paid by CRMC were $4,000, $371,000 and $77,000 for Class R-1, R-2 and R-3, respectively. Administrative services fees are presented gross of any payments made by CRMC. Each 529 share class is subject to an additional annual administrative services fee of 0.10% of its respective average daily net assets; this fee is payable to the Commonwealth of Virginia for the maintenance of the CollegeAmerica plan. Although these amounts are included with administrative services fees on the accompanying financial statements, the Commonwealth of Virginia is not considered a related party.

Expenses under the agreements described above for the year ended August 31, 2006, were as follows (dollars in thousands):

Deferred trustees’ compensation - Since the adoption of the deferred compensation plan in 1993, trustees who are unaffiliated with CRMC may elect to defer the cash payment of part or all of their compensation. These deferred amounts, which remain as liabilities of the fund, are treated as if invested in shares of the fund or other American Funds. These amounts represent general, unsecured liabilities of the fund and vary according to the total returns of the selected funds. Trustees’ compensation of $66,000, shown on the accompanying financial statements, includes $50,000 in current fees (either paid in cash or deferred) and a net increase of $16,000 in the value of the deferred amounts.

Affiliated officers and trustees - Officers and certain trustees of the fund are or may be considered to be affiliated with CRMC, AFS and AFD. No affiliated officers or trustees received any compensation directly from the fund.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trustees and Shareholders of The American Funds Income Series - U.S. Government Securities Fund:

We have audited the accompanying statement of assets and liabilities of The American Funds Income Series - U.S. Government Securities Fund (the “Fund”), including the investment portfolio, as of August 31, 2006, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the periods presented. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of August 31, 2006, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of The American Funds Income Series - U.S. Government Securities Fund as of August 31, 2006, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the periods presented, in conformity with accounting principles generally accepted in the United States of America.
